Nārada says that "If somebody neglects all other duty, all other duty . . ." Tyaktvā sva-dharmam. Sva-dharmam means every particular man has got some particular form of duty. Every particular man. You have got some duty, I have got some duty, everyone. Nobody is dutiless. Now, Nārada says: "Even sacrificing the so-called duties, if one takes absolutely unto the spiritual life, then he is not loser. He's not loser. On the contrary, one who does not take up this important task and remain engaged in the so-called duties, he's a loser." He's a loser. It is a very important point.
Now, Bhagavad-gītā also confirms that, once begun this spiritual life, then he's not loser in this sense, that his human life is guaranteed in the next birth. In the ordinary duty, you do not know whether you'll have again this human body or not. There is no certainty. That will depend on your quality of work. But here, if you begin your spiritual life, sacrificing all other duties, then your next life as human being is guaranteed. Guaranteed. You'll find in Bhagavad-gītā that śucīnāṁ śrīmatāṁ gehe yoga-bhraṣṭo 'bhijāyate sanja (BG 6.41).
Bhraṣṭa. Bhraṣṭa means one, yoga-bhraṣṭa, one who is prosecuting the yoga system . . . the yoga sys . . . 'yoga system I have already explained. Yoga system means the transcendental process by which we realize ourself, we link up our life with self-realization. That is called yoga.
