After every dissolution of the material cosmos, all the living entities take shelter in the body of Kāraṇodakaśāyī Viṣṇu, and when creation takes place again, they come forth from His body in their various species to resume their activities. Why does the creation take place in such a way that the living entities are put into conditioned life to suffer the threefold miseries imposed upon them by the material nature? Here the Lord says to Dakṣa, “You desire to benefit all living entities, and that is also My desire.” The living entities who come in contact with the material world are meant to be corrected. All the living entities within this material world have revolted against the service of the Lord, and therefore they remain within this material world as ever conditioned, nitya-baddha, taking birth again and again. There is a chance, of course, of their being liberated, but nevertheless the conditioned souls, not taking advantage of this opportunity, continue in a life of sense enjoyment, and thus they are punished by birth and death again and again. This is the law of nature. As the Lord says in Bhagavad-gītā (7.14):

daivī hy eṣā guṇa-mayī
 mama māyā duratyayā
mām eva ye prapadyante
 māyām etāṁ taranti te

“This divine energy of Mine, consisting of the three modes of material nature, is difficult to overcome. But those who have surrendered unto Me can easily cross beyond it.” Elsewhere in Bhagavad-gītā (15.7) the Lord says:

mamaivāṁśo jīva-loke
 jīva-bhūtaḥ sanātanaḥ
manaḥ ṣaṣṭhānīndriyāṇi
 prakṛti-sthāni karṣati

“The living entities in this conditioned world are My eternal, fragmental parts. Due to conditioned life, they are struggling very hard with the six senses, which include the mind.” The living entity’s struggle for existence within the material world is due to his rebellious nature. Unless a living entity surrenders to Kṛṣṇa, he must continue this life of struggle.

The Kṛṣṇa consciousness movement is not a fad. It is a bona fide movement intended to promote the welfare of all conditioned souls by trying to elevate everyone to the platform of Kṛṣṇa consciousness. If one does not come to this platform, he must continue in material existence perpetually, sometimes in the upper planets and sometimes in the lower planets. As confirmed in Caitanya-caritāmṛta (Madhya 20.118), kabhu svarge uṭhāya, kabhu narake ḍubāya: the conditioned soul sometimes descends into nescience and sometimes gets some relief by being relatively freed from it. This is the life of the conditioned soul.

Prajāpati Dakṣa is trying to benefit the conditioned souls by begetting them to give them a life with a chance for liberation. Liberation means surrender to Kṛṣṇa. If one begets children with the purpose of training them to surrender to Kṛṣṇa, fatherhood is very good. Similarly, when the spiritual master trains the conditioned souls to become Kṛṣṇa conscious, his position is successful. If one gives the conditioned souls a chance to become Kṛṣṇa conscious, all his activities are approved by the Supreme Personality of Godhead, who is extremely pleased, as stated here (prīto ’ham). Following the examples of the previous ācāryas, all the members of the Kṛṣṇa consciousness movement should try to benefit the conditioned souls by inducing them to become Kṛṣṇa conscious and giving them all facilities to do so. Such activities constitute real welfare work. By such activities, a preacher or anyone who endeavors to spread Kṛṣṇa consciousness is recognized by the Supreme Personality of Godhead. As the Lord Himself confirms in Bhagavad-gītā (18.68-69):

ya idaṁ paramaṁ guhyaṁ
 mad-bhakteṣv abhidhāsyati
bhaktiṁ mayi parāṁ kṛtvā
 mām evaiṣyaty asaṁśayaḥ

na ca tasmān manuṣyeṣu
 kaścin me priya-kṛttamaḥ
bhavitā na ca me tasmād
 anyaḥ priyataro bhuvi

“For one who explains the supreme secret to the devotees, devotional service is guaranteed, and at the end he will come back to Me. There is no servant in this world more dear to Me than he, nor will there ever be one more dear.”
