People are generally after four principles of happiness: being religious, being economically developed, being very good candidate for satisfying senses, and when one is frustrated to derive any happiness from these three principles, he wants liberation, nirbheda-brahmānu-sandhana.
Pradyumna: "This is doom for him because this human form of life is meant for getting out of the material contamination. By the advancement of material knowledge, people are becoming more and more entangled in material existence. They have no hope of being liberated from this catastrophe. In the Hari-bhakti-sudhodaya it is stated that Prahlāda Mahārāja, a great devotee of the Lord, prayed to Nṛsiṁha-deva (the half-lion, half-man incarnation), as follows: 'My dear Lord, I repeatedly pray unto Your lotus feet that I may simply be stronger in devotional service. I simply pray that my Kṛṣṇa consciousness may be more strong and steady, because happiness derived out of Kṛṣṇa consciousness and devotional service is so powerful that with it one can have all the other perfections of religiousness, economic development, sense gratification and even the attainment of liberation from material existence.' Actually, a pure devotee does not aspire after any of these perfections because the happiness derived from devotional service in Kṛṣṇa consciousness is so transcendental and so unlimited that no other happiness can be compared with it. It is said that even one drop of happiness in Kṛṣṇa consciousness stands beyond comparison with an ocean of happiness derived from any other activity. Thus, any person who has developed even a little quantity of pure devotional service can very easily kick out all the other kinds of happiness derived from religiousness, economic development, sense gratification and liberation."
Prabhupāda: Dharmārtha-kāma-mokṣa (SB 4.8.41). There are, people are generally after four principles of happiness: being religious, being economically developed, being very good candidate for satisfying senses, and when one is frustrated to derive any happiness from these three principles, he wants liberation, nirbheda-brahmānu-sandhana. That is also not actual happiness, because, as I was explaining this morning, that even one merges into the Brahman effulgence after severe penances and austerity, there is chance of falling down. There is chance. Āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanti (SB 10.2.32). Paraṁ pada is to merge into the Brahman effulgence existence. But from there also, one falls down, as I was giving the example of many big sannyāsīs in the modern age. They are very learned scholar. They took to sannyāsa, giving up this world as false, but again, after some time, they come to politics, sociology. That means that is their falldown. Because they could not actually taste the Brahman, brahmānanda, for which they sacrificed everything... So brahmānanda is not such a thing that one will come again to this false platform which they rejected as brahma satyaṁ jagan mithyā. If jagat is mithyā, then why such exalted persons, who gave up everything for brahmānanda... That means they could not taste brahmānanda. Therefore they fell down. Go on.
