Śāstra says, "This kind of laboring hard simply for satisfaction of senses is the business of the hog and pig. It is not the business of the human being." Nāyaṁ deho deha-bhājāṁ nṛloke kaṣṭān kāmān arhate viḍ-bhujāṁ ye (SB 5.5.1).
So human society, they should rectify their mode of civilization by taking this Kṛṣṇa consciousness movement. Then they will be happy. Otherwise, if they keep themself in ignorance, ajñaḥ, dehy ajñaḥ, then ajita-ṣaḍ-varga: he will never be able to control the senses. The yoga system, haṭha-yoga system, is meant for this class of rascals, ajita. Yoga indriya-saṁyamaḥ. Real meaning of yoga means controlling the senses. So because everyone is ajita-ṣaḍ-varga—ajita means not conquered—so those who are too much addicted in the bodily concept of life, for them this haṭha-yoga is prescribed. The purpose is to control the senses, not that to reduce fat or something else. No. Real purpose is yoga indriya-saṁyamaḥ. Because unless we control the senses, we remain in ignorance, blind, and go on. Ajita-ṣaḍ-vargo necchan. Necchan. Na icchan. If we do not try, then even though I do not want to do something, even I. . . On the cigarette package there is that "It is not good for health." So I do not like that my health should be ruined, but necchan, I am compelled to smoke. This is our position.
