One should satisfy the senses only insomuch as required for self-preservation, and not for sense gratification. Because the body is made of senses, which also require a certain amount of satisfaction, there are regulative directions for satisfaction of such senses. But the senses are not meant for unrestricted enjoyment. For example, marriage or the combination of a man with a woman is necessary for progeny, but it is not meant for sense enjoyment. In the absence of voluntary restraint, there is propaganda for family planning, but foolish men do not know that family planning is automatically executed as soon as there is search after the Absolute Truth. Seekers of the Absolute Truth are never allured by unnecessary engagements in sense gratification because the serious students seeking the Absolute Truth are always overwhelmed with the work of researching the Truth. In every sphere of life, therefore, the ultimate end must be seeking after the Absolute Truth, and that sort of engagement will make one happy because he will be less engaged in varieties of sense gratification.
(Srimad Bhagavatam-----1:2:10-----purport).

If the father and the mother do not undertake the process of spiritual family planning and simply beget children out of passion only, their children are called dvija-bandhus. These dvija-bandhus are certainly not as intelligent as the children of the regular twice-born families. The dvija-bandhus are classified with the śūdras and the woman class, who are by nature less intelligent. The śūdras and the woman class do not have to undergo any saṁskāra save and except the ceremony of marriage.
(Srimad Bhagavatam-----1:4:25-----purport).

There are different transcendental activities of the Lord, and each and every one of them is competent to bestow the desired result, provided the hearing process is perfect. In the Bhāgavatam the activities of the Lord begin from His dealings with the Pāṇḍavas. There are many other pastimes of the Lord in connection with His dealings with the asuras and others. And in the Tenth Canto the sublime dealings with His conjugal associates, the gopīs, as well as with His married wives at Dvārakā are mentioned. Since the Lord is absolute, there is no difference in the transcendental nature of each and every dealing of the Lord. But sometimes people, in an unauthorized hearing process, take more interest in hearing about His dealings with the gopīs. Such an inclination indicates the lusty feelings of the hearer, so a bona fide speaker of the dealings of the Lord never indulges in such hearings.
(Srimad Bhagavatam-----1:8:36-----purport).

By the order of his mother, Satyavatī, who was later married to Mahārāja Śantanu, and by the request of Bhīṣmadeva, the eldest son of Mahārāja Śantanu by his first wife, the Ganges, he begot three brilliant sons, whose names are Dhṛtarāṣṭra, Pāṇḍu and Vidura. The Mahābhārata was compiled by Vyāsadeva after the Battle of Kurukṣetra and after the death of all the heroes of Mahābhārata. It was first spoken in the royal assembly of Mahārāja Janamejaya, the son of Mahārāja Parīkṣit.
(Srimad Bhagavatam-----1:9:6-7-----purport).

Paraśurāma is so old that he met both Rāma and Kṛṣṇa at different times. He fought with Rāma, but he accepted Kṛṣṇa as the Supreme Personality of Godhead. He also praised Arjuna when he saw him with Kṛṣṇa. When Bhīṣma refused to marry Ambā, who wanted him to become her husband, Ambā met Paraśurāma, and by her request only, he asked Bhīṣmadeva to accept her as his wife. Bhīṣma refused to obey his order, although he was one of the spiritual masters of Bhīṣmadeva. Paraśurāma fought with Bhīṣmadeva when Bhīṣma neglected his warning. Both of them fought very severely, and at last Paraśurāma was pleased with Bhīṣma and gave him the benediction of becoming the greatest fighter in the world.
(Srimad Bhagavatam-----1:9:6-7-----purport).

Kaśyapa: One of the prajāpatis, the son of Marīci and one of the sons-in-law of Prajāpati Dakṣa. He is the father of the gigantic bird Garuḍa, who was given elephants and tortoises as eatables. He married thirteen daughters of Prajāpati Dakṣa, and their names are Aditi, Diti, Danu, Kāṣṭhā, Ariṣṭā, Surasā, Ilā, Muni, Krodhavaśā, Tāmrā, Surabhi, Saramā and Timi. He begot many children, both demigods and demons, by those wives. From his first wife, Aditi, all the twelve Ādityas were born; one of them is Vāmana, the incarnation of Godhead. This great sage, Kaśyapa, was also present at the time of Arjuna's birth. He received a presentation of the whole world from Paraśurāma, and later on he asked Paraśurāma to go out of the world. His other name is Ariṣṭanemi. He lives on the northern side of the universe.
(Srimad Bhagavatam-----1:9:8-----purport).

Kṛṣṇa was to start for Dvārakā, His own kingdom, after the Battle of Kurukṣetra and Yudhiṣṭhira's being enthroned, but to oblige the request of Mahārāja Yudhiṣṭhira and to show special mercy to Bhīṣmadeva, Lord Kṛṣṇa stopped at Hastināpura, the capital of the Pāṇḍavas. The Lord decided to stay especially to pacify the aggrieved King as well as to please Subhadrā, sister of Lord Śrī Kṛṣṇa. Subhadrā was especially to be pacified because she lost her only son, Abhimanyu, who was just married. The boy left his wife, Uttarā, mother of Mahārāja Parīkṣit. The Lord is always pleased to satisfy His devotees in any capacity. Only His devotees can play the parts of His relatives. The Lord is absolute.
(Srimad Bhagavatam-----1:10:7-----purport).

When He descends, He exhibits superhuman acts just to prove His supreme right, and materialists like Rāvaṇa, Hiraṇyakaśipu and Kaṁsa are sufficiently punished. He acts in a manner which no one can imitate. For example, the Lord, when He appeared as Rāma, bridged the Indian Ocean. When He appeared as Kṛṣṇa, from His very childhood He showed superhuman activities by killing Pūtanā, Aghāsura, Śakaṭāsura, Kāliya, etc., and then His maternal uncle Kaṁsa. When He was at Dvārakā He married 16,108 queens, and all of them were blessed with a sufficient number of children. The sum total of His personal family members amounted to about ten million, popularly known as the Yadu-vaṁśa. And again, during His lifetime, He managed to vanquish them all. He is famous as the Govardhana-dhārī Hari because He lifted at the age of only seven the hill known as Govardhana. The Lord killed many undesirable kings in His time, and as a kṣatriya He fought chivalrously. He is famous as the asamaurdhva, unparalleled. No one is equal to or greater than Him.
(Srimad Bhagavatam-----1:10:25-----purport).

The Lord is always perfect in Himself, and thus He has no hankering for Himself. He, however, becomes a master, a friend, a son or a husband to fulfill the intense love of the devotee concerned. Herein two classes of devotees of the Lord are mentioned in the stage of conjugal love. One is svakīya, and the other is parakīya. Both of them are in conjugal love with the Personality of Godhead Kṛṣṇa. The queens at Dvārakā were svakīya, or duly married wives, but the damsels of Vraja were young friends of the Lord while He was unmarried. The Lord stayed at Vṛndāvana till the age of sixteen, and His friendly relations with the neighboring girls were in terms of parakīya. These girls, as well as the queens, underwent severe penances by taking vows, bathing and offering sacrifices in the fire, as prescribed in the scriptures. The rites, as they are, are not an end in themselves, nor are fruitive action, culture of knowledge or perfection in mystic powers ends in themselves. They are all means to attain to the highest stage of svarūpa, to render constitutional transcendental service to the Lord.
(Srimad Bhagavatam-----1:10:28-----purport).

Exceptionally qualified daughters of powerful kings were allowed to make a choice of their own bridegrooms in open competition, and such ceremonies were called svayaṁvara, or personal selection of the bridegroom. Because the svayaṁvara was an open competition between the rival and valiant princes, such princes were invited by the father of the princess, and usually there were regular fights between the invited princely order in a sporting spirit. But it so happened that sometimes the belligerent princes were killed in such marriage-fighting, and the victorious prince was offered the trophy princess for whom so many princes died. Rukmiṇī, the principal queen of Lord Kṛṣṇa, was the daughter of the King of Vidarbha, who wished that his qualified and beautiful daughter be given away to Lord Kṛṣṇa. But her eldest brother wanted her to be given away to King Śiśupāla, who happened to be a cousin of Kṛṣṇa. So there was open competition, and as usual Lord Kṛṣṇa emerged successful, after harassing Śiśupāla and other princes by His unrivalled prowess. Rukmiṇī had ten sons, like Pradyumna. There were other queens also taken away by Lord Kṛṣṇa in a similar way. Full description of this beautiful booty of Lord Kṛṣṇa will be given in the Tenth Canto. There were 16,100 beautiful girls who were daughters of many kings and were forcibly stolen by Bhaumāsura, who kept them captive for his carnal desire. These girls prayed piteously to Lord Kṛṣṇa for their deliverance, and the merciful Lord, called by their fervent prayer, released them all by fighting and killing Bhaumāsura. All these captive princesses were then accepted by the Lord as His wives, although in the estimation of society they were all fallen girls. The all-powerful Lord Kṛṣṇa accepted the humble prayers of these girls and married them with the adoration of queens. So altogether Lord Kṛṣṇa had 16,108 queens at Dvārakā, and in each of them He begot ten children. All these children grew up, and each had as many children as the father. The aggregate of the family numbered 10,000,000.
