Human prosperity flourishes by natural gifts and not by gigantic industrial enterprises. The gigantic industrial enterprises are products of a godless civilization, and they cause the destruction of the noble aims of human life. The more we go on increasing such troublesome industries to squeeze out the vital energy of the human being, the more there will be unrest and dissatisfaction of the people in general. Srimad Bhagavatam 1.8.40

Devotional service means to accept favorable and reject unfavorable. This is called śaraṇāgati. Surrender means to accept favorable things, how I can make progress towards Kṛṣṇa,
Srila Prabhupada realized that varnasrama allows people to succeed in spiritual life. When a follower reminds him that Lord Caitanya rejected varnasrama, he replies, “Our position is different.”
By developing daivi varnasrama – adjusted for modern conditions – we can give an opportunity for every person, regardless of their individual material nature, to obtain spiritual perfection.
