Śrīla Bhaktivinoda Ṭhākura has composed a song in which he addresses himself: "O living entity, get up! How long shall you sleep on the lap of māyā? Now you have the opportunity of possessing a human form of body; now try to get up and realize yourself." The Vedas also declare, "Get up! Get up! You have the opportunity, the boon of the human form of life—now realize yourself." These are the Vedic injunctions.
(Srimad Bhagavatam----4:9:4----purport).

Śrīla Bhaktivinoda Ṭhākura advised: "My friend, you are being washed away in material nature's waves of time. Please try to understand that you are the eternal servant of the Lord. Then everything will stop, and you will be eternally happy."
(Srimad Bhagavatam----4:11:21----purport).

Śrīla Bhaktivinoda Ṭhākura sings: "My dear Lord, whatever I have—even my mind, the center of all material necessities. namely my home, my body and whatever I have in connection with this body—I now surrender unto You. You are now completely independent to act however You like. If You like, You can kill me, and if You like, You can save me. In any case, I am Your eternal servant, and You have every right to do whatever You like."
(Srimad Bhagavatam----4:17:30----purport).

According to Bhaktivinoda Ṭhākura also, a husband and wife can turn the home into a place as good as Vaikuṇṭha, even while in this material world. Being absorbed in Kṛṣṇa consciousness, even in this world husband and wife can live in Vaikuṇṭha simply by installing the Deity of the Lord within the home and serving the Deity according to the directions of the śāstras. In this way, they will never feel the sex urge. That is the test of advancement in devotional service. One who is advanced in devotional service is never attracted by sex life, and as soon as one becomes detached from sex life and proportionately attached to the service of the Lord, he actually experiences living in the Vaikuṇṭha planets. In the ultimate issue, there is actually no material world, but when one forgets the service of the Lord and engages himself in the service of his senses, he is said to be living in the material world.
(Srimad Bhagavatam----4:23:29----purport).

Śrīla Bhaktivinoda Ṭhākura has sung a verse indicating that the tongue is the most formidable enemy among all the senses. If one can control the tongue, he can easily control the other senses. The tongue can be controlled only by eating prasāda offered to the Deity.
(Srimad Bhagavatam----4:24:38----purport).

The material conditions are described in this verse as guṇa-pravāha, the flowing of the three modes of material nature. Śrīla Bhaktivinoda Ṭhākura therefore says in a song, miche māyāra vaśe, yāccha bhese', khāccha hābuḍubu, bhāi: "Why are you suffering? Why are you sometimes being drowned in the waves of material nature and sometimes coming to the surface?" Jīva kṛṣṇa-dāsa, ei viśvāsa, karle ta' āra duḥkha nāi: "Please therefore accept yourself as the servant of Kṛṣṇa. Then you will be freed from all miseries." As soon as one surrenders to Kṛṣṇa and accepts the perfect standard of knowledge, which is Bhagavad-gītā as it is, he then comes out of the material modes of nature and does not fall down and lose his knowledge.
(Srimad Bhagavatam----4:26:8----purport).

Śrīla Bhaktivinoda Ṭhākura has sung: vṛddha kāla āola saba sukha bhāgala. When one becomes old, it becomes impossible to enjoy material happiness. Generally people think that religion and piety come at the end of life, and at this time one generally becomes meditative and takes to some so-called yogic process to relax in the name of meditation.
(Srimad Bhagavatam----4:27:17----purport).

Śrīla Bhaktivinoda Ṭhākura has sung:
anādi karama-phale, paḍi' bhavārṇava-jale,
taribāre nā dekhi upāya
ei viṣaya-halāhale, divā-niśi hiyā jvale,
mana kabhu sukha nāhi pāya
"Because of my past fruitive activities, I have now fallen into an ocean of nescience. I cannot find any means to get out of this great ocean, which is indeed like an ocean of poison. We are trying to be happy through sense enjoyment, but actually that so-called enjoyment is like food that is too hot and causes burning in the heart. I feel a burning sensation constantly, day and night, and thus my mind cannot find satisfaction."
(Srimad Bhagavatam----4:28:27----purport).

Śrīla Bhaktivinoda Ṭhākura sings:
miche māyāra vaśe, yāccha bhese',
khāccha hābuḍubu, bhai
jīva kṛṣṇa-dāsa, ei viśvāsa,
karle ta' āra duḥkha nāi
"My dear living entities, you are being carried away by the waves of material nature. Sometimes you are on the surface, sometimes you are being drowned. In this way your eternal life is being spoiled. If you simply catch hold of Kṛṣṇa and take shelter of His lotus feet, you will once again get free from all the miserable material conditions."
(Srimad Bhagavatam----4:28:60----purport).

The living entity's position is herein likened to a dog's. By chance a dog may have a very rich owner, and by chance he may become a street dog. As the dog of a rich man, he will live very opulently. Sometimes in Western countries we hear of a master leaving millions of dollars to a dog in his will. Of course, there are many dogs loitering in the street without food. Therefore, to liken the conditional existence of the living entity to that of a dog is very appropriate. An intelligent human being, however, can understand that if he has to live the life of a dog, he had best become Kṛṣṇa's dog. In the material world a dog is sometimes elevated and is sometimes on the street, but in the spiritual world, Kṛṣṇa's dog is perpetually, eternally happy. ŚrīlaBhaktivinoda Ṭhākura has therefore sung: vaiṣṇava ṭhākura tomāra kukura baliyā jānaha more. In this way Bhaktivinoda Ṭhākura offers to become a Vaiṣṇava's dog. A dog always keeps himself at his master's door and does not allow any person unfavorable to the master to enter. Similarly, one should engage in the service of a Vaiṣṇava and try to please him in every respect.
(Srimad Bhagavatam----4:29:30:31----purport).

Generally people are very much attracted to the fruitive activities sanctioned in the Vedic rituals. One may be very much attracted to becoming elevated to heavenly planets by performing great sacrifices, like those of King Barhiṣmān. Śrī Nārada Muni wanted to stop King Barhiṣmān from engaging in such fruitive activities. Therefore he is now directly telling him, "Don't be interested in such temporary benefits." In modern civilization people are very much interested in exploiting the resources of material nature through the methods of science. Indeed, this is considered advancement. This is not actually advancement, however, but is simply pleasing to hear. Although we are advancing according to such concocted methods, we are forgetting our real purpose. Bhaktivinoda Ṭhākura therefore says, jaḍa-vidyā yata māyāra vaibhava tomāra bhajane bādhā: "Materialistic studies are the glare of māyā only, for they are an obstacle to spiritual progress."
(Srimad Bhagavatam----4:29:47----purport).
