O mother earth, the Supreme Personality of Godhead, Hari, incarnated Himself as Lord Śrī Kṛṣṇa just to unload your heavy burden. All His activities here are transcendental, and they cement the path of liberation. You are now bereft of His presence. You are probably now thinking of those activities and feeling sorry in their absence.
(Srimad Bhagavatam----1:6:23----translation).

To effect the perfection of human life there is cooperation between men and demigods, sages, denizens of the Pitṛloka, devotees of the Lord and the scientific system of varṇa and āśrama orders of life. The distinction between human life and animal life therefore begins with the scientific system of varṇa and āśrama, guided by the experience of the sages in relation with the demigods, gradually rising to the summit of reestablishing our eternal relation with the Supreme Absolute Truth, the Personality of Godhead, Lord Śrī Kṛṣṇa. When God-made varṇāśrama-dharma, which is strictly meant for developing animal consciousness into human consciousness and human consciousness into godly consciousness, is broken by advancement of foolishness, the whole system of peaceful and progressive life is at once disturbed. In the age of Kali, the first attack of the venomous snake strikes against the God-made varṇāśrama-dharma, and thus a person properly qualified as a brāhmaṇa is called a śūdra, and a śūdra by qualification is passing as a brāhmaṇa, all on a false birthright claim. To become a brāhmaṇa by a birthright claim is not at all bona fide, although it may be a fulfillment of one of the conditions. But the real qualification of a brāhmaṇa is to control the mind and the senses, and to cultivate tolerance, simplicity, cleanliness, knowledge, truthfulness, devotion and faith in the Vedic wisdom. In the present age, consideration of the necessary qualification is being neglected, and the false birthright claim is being supported even by a popular, sophisticated poet, the author of Rāma-carita-mānasa.
This is all due to the influence of the age of Kali. Thus mother earth, represented as a cow, was lamenting the regrettable condition.
(Srimad Bhagavatam----1:6:31----purport).

The asuras want to enjoy a life of sense gratification, even at the cost of others' happiness. In order to fulfill this ambition, the asuras, especially atheistic kings or state executive heads, try to equip themselves with all kinds of deadly weapons to bring about a war in a peaceful society. They have no ambition other than personal aggrandizement, and thus mother earth feels overburdened by such undue increases of military strength. By increase of the asuric population, those who follow the principles of religion become unhappy, especially the devotees, or devas.
(Srimad Bhagavatam----1:6:34----purport).

The kṣatriya, or the man who is qualified to protect the sufferers, is meant to rule the state. Untrained lower-class men, or men without ambition to protect the sufferers, cannot be placed on the seat of an administrator. Unfortunately, in the age of Kali the lower-class men, without training, occupy the post of a ruler by strength of popular votes, and instead of protecting the sufferers, such men create a situation quite intolerable for everyone. Such rulers illegally gratify themselves at the cost of all comforts of the citizens, and thus the chaste mother earth cries to see the pitiable condition of her sons, both men and animals. That is the future of the world in the age of Kali, when irreligiosity prevails most prominently. And in the absence of a suitable king to curb irreligious tendencies, educating the people systematically in the teaching of Śrīmad-Bhāgavatam will clear up the hazy atmosphere of corruption, bribery, blackmail, etc.
(Srimad Bhagavatam----1:17:27----purport).

Mahārāja Parīkṣit, therefore, like his grandfather Arjuna, collected all illicit gold kept for the propensities of Kali and employed it in the saṅkīrtana-yajña, as per instruction of the Śrīmad-Bhāgavatam. As we have suggested before, one's accumulated wealth may be divided into three parts for distribution, namely fifty percent for the service of the Lord, twenty-five percent for the family members and twenty-five percent for personal necessities. Spending fifty percent for the service of the Lord or for propagation of spiritual knowledge in society by way of the saṅkīrtana-yajña is the maximum display of human mercy. people of the world are generally in darkness regarding spiritual knowledge, especially in regard to the devotional service of the Lord, and therefore to propagate the systematic transcendental knowledge of devotional service is the greatest mercy that one can show in this world. When everyone is taught to sacrifice fifty percent of his accumulated gold for the Lord's service, certainly austerity, cleanliness and mercy automatically ensue, and thus the lost three legs of the personality of religion are automatically established. When there is sufficient austerity, cleanliness, mercy and truthfulness, naturally mother earth is completely satisfied, and there is very little chance for Kali to infiltrate the structure of human society.
(Srimad Bhagavatam----1:17:42----purport).

The impersonalists argue that there is no use in worshiping the Lord when everything is nothing but the Lord Himself. The personalist, however, worships the Lord out of a great sense of gratitude, utilizing the ingredients born out of the bodily limbs of the Lord. The fruits and flowers are available from the body of the earth, and yet mother earth is worshiped by the sensible devotee with ingredients born from the earth. Similarly, mother Ganges is worshiped by the water of the Ganges, and yet the worshiper enjoys the result of such worship. Worship of the Lord is also performed by the ingredients born from the bodily limbs of the Lord, and yet the worshiper, who is himself a part of the Lord, achieves the result of devotional service to the Lord. While the impersonalist wrongly concludes that he is the Lord himself, the personalist, out of a great gratitude, worships the Lord in devotional service, knowing perfectly well that nothing is different from the Lord. The devotee therefore endeavors to apply everything in the service of the Lord because he knows that everything is the property of the Lord and that no one can claim anything as one's own. This perfect conception of oneness helps the worshiper in being engaged in His loving service, whereas the impersonalist, being falsely puffed up, remains a nondevotee forever, without being recognized by the Lord.
(Srimad Bhagavatam----2:6:23----purport).

O Lord, for the residential purposes of all inhabitants, both moving and nonmoving, this earth is Your wife, and You are the supreme father. We offer our respectful obeisances unto You, along with mother earth, in whom You have invested Your own potency, just as an expert sacrificer puts fire in the araṇi wood.
The so-called law of gravitation which sustains the planets is described herein as the potency of the Lord. This potency is invested by the Lord in the way that an expert sacrificial brāhmaṇa puts fire in the araṇi wood by the potency of Vedic mantras. By this arrangement the world becomes habitable for both the moving and nonmoving creatures. The conditioned souls, who are residents of the material world, are put in the womb of mother earth in the same way the seed of a child is put by the father in the womb of the mother. This conception of the Lord and the earth as father and mother is explained in Bhagavad-gītā (14.4). Conditioned souls are devoted to the motherland in which they take their birth, but they do not know their father. The mother is not independent in producing children. Similarly, material nature cannot produce living creatures unless in contact with the supreme father, the Supreme Personality of Godhead. Śrīmad-Bhāgavatam teaches us to offer obeisances unto the mother along with the Father, the Supreme Lord, because it is the Father only who impregnates the mother with all energies for the sustenance and maintenance of all living beings, both moving and nonmoving.
(Srimad Bhagavatam----3:13:42----translation and purport).

Just as a mother produces various children, both male and female, the womb of mother earth produces all kinds of living entities in various shapes. Thus it is possible for mother earth to take on innumerable shapes. At this time, in order to avoid the wrath of King Pṛthu, she took the shape of a cow. Since a cow is never to be killed, mother earth thought it wise to take the shape of a cow in order to avoid King Pṛthu's arrows. King Pṛthu, however, could understand this fact, and therefore he did not stop chasing the cow-shaped earth.
(Srimad Bhagavatam----4:17:14----purport).

The cow-shaped earth addressed King Pṛthu as dharma jña, which refers to one who knows the principles of religion. The principles of religion dictate that a woman, a cow, a child, a brāhmaṇa and an old man must be given all protection by the king or anyone else. Consequently mother earth took the shape of a cow. She was also a woman. Thus she appealed to the King as one who knows the principles of religion. Religious principles also dictate that one is not to be killed if he surrenders. She reminded King Pṛthu that not only was he an incarnation of God, but he was situated as the King of the earth as well. Therefore his duty was to excuse her.
(Srimad Bhagavatam----4:17:18----purport).

After hearing the instructive advice of Śukrācārya, Bali Mahārāja became contemplative. Because it is the duty of a householder to maintain the principles of religion, economic development and sense gratification, Bali Mahārāja thought it improper to withdraw his promise to the brahmacārī. To lie or fail to honor a promise given to a brahmacārī is never proper, for lying is the most sinful activity. Everyone should be afraid of the sinful reactions to lying, for mother earth cannot even bear the weight of a sinful liar.
(Srimad Bhagavatam----8:20--summary).

On the surface of the earth there are many great mountains and oceans that are very heavy, and mother earth has no difficulty carrying them. But she feels very much overburdened when she carries even one person who is a liar. It is said that in Kali-yuga lying is a common affair: māyaiva vyāvahārike (S.B.12:2:3). Even in the most common dealings, people are accustomed to speaking so many lies. No one is free from the sinful reactions of speaking lies. Under the circumstances, one can just imagine how this has overburdened the earth, and indeed the entire universe.
(Srimad Bhagavatam----8:20:4----purport).

Once when the entire world was overburdened by the increasing military power of demons in the form of kings, mother earth assumed the shape of a cow and approached Lord Brahmā for relief, Sympathetic to mother earth's lamentation, Brahmā, accompanied by Lord Śiva and other demigods, took the cow-shaped mother earth to the shore of the milk ocean, where he offered prayers to please Lord Viṣṇu, who lay there on an island in transcendental ecstasy. Brahmā thereafter understood the advice of Mahā-Viṣṇu, who informed him that He would appear on the surface of the earth to mitigate the burden created by the demons. The demigods, along with their wives, should appear there as associates of Lord Kṛṣṇa in the family of Yadu to increase the sons and grandsons in that dynasty. By the will of Lord Kṛṣṇa, Anantadeva would appear first, as Balarāma, and Kṛṣṇa's potency, yogamāyā, would also appear. Brahmā informed mother earth about all this, and then he returned to his own abode.
(Srimad Bhagavatam----10:1--summary).

Thereafter, having heard of the distress of mother earth, Lord Brahmā, with mother earth, Lord Śiva and all the other demigods, approached the shore of the ocean of milk.
After Lord Brahmā understood the precarious condition of the earth, he first visited the demigods headed by Lord Indra, who are in charge of the various affairs of this universe, and Lord Śiva, who is responsible for annihilation. Both maintenance and annihilation go on perpetually, under the order of the Supreme Personality of Godhead. As stated in Bhagavad-gītā (4.8), paritrāṇāya sādhūnāṁ vināśāya ca duṣkṛtām. Those who are obedient to the laws of God are protected by different servants and demigods, whereas those who are undesirable are vanquished by Lord Śiva. Lord Brahmā first met all the demigods, including Lord Śiva. Then, along with mother earth, they went to the shore of the ocean of milk, where Lord Viṣṇu lies on a white island, Śvetadvīpa.
(Srimad Bhagavatam----10:1:19----translation and purport).

It has already been discussed that mother earth implored Lord Brahmā to give her relief from the distress created by the burdensome demons and that Lord Brahmā informed her that Lord Kṛṣṇa Himself was going to appear. Kṛṣṇa says in Bhagavad-gītā (4.8):
paritrāṇāya sādhūnāṁ
vināśāya ca duṣkṛtām
dharma-saṁsthāpanārthāya
sambhavāmi yuge yuge
Whenever there is a burden created by the demons and whenever the innocent devotees are distressed by demoniac rulers, the Lord appears in due course of time to kill the demons with the assistance of His real representatives, who are technically called demigods.
(Srimad Bhagavatam----10:1:64----purport).

When Lord Kṛṣṇa heard the prayers of mother earth, He immediately assured her of immunity from all fearful situations. He said to Bhagadatta, “Don’t be afraid.” Then He entered the palace of Bhaumāsura, which was equipped with all kinds of opulences. In the palace of Bhaumāsura, Lord Kṛṣṇa saw 16,100 young princesses, who had been kidnapped and held captive there. When the princesses saw the Supreme Personality of Godhead, Kṛṣṇa, enter the palace, they immediately became captivated by the beauty of the Lord and prayed for His causeless mercy. Within their minds, they decided to accept Lord Kṛṣṇa as their husband without hesitation. Each one of them prayed to Providence that Kṛṣṇa might become her husband. Sincerely and seriously, they offered their hearts to the lotus feet of Kṛṣṇa with an unalloyed devotional attitude. As the Supersoul in everyone's heart, Kṛṣṇa could understand their uncontaminated desire, and He agreed to accept them as His wives.
(Krsna Book).

There are seven kinds of mothers, according to Vedic injunction: the real mother, the wife of a teacher or spiritual master, the wife of a king, the wife of a brāhmaṇa, the cow, the nurse and mother earth. Because Pūtanā came to take Kṛṣṇa on her lap and offer her breast milk to be sucked by Him, she was accepted by Kṛṣṇa as one of His mothers. That is considered to be another reason He closed His eyes: He had to kill a nurse or mother. But His killing of His mother or nurse was no different from His love for His real mother or His foster mother, Yaśodā. We further understand from Vedic information that Pūtanā was also treated as a mother and given the same facility as Yaśodā. As Yaśodā was given liberation from the material world, Pūtanā was also given liberation.
