Then, if you say that "It may be that I cannot fulfill cent percent Kṛṣṇa consciousness in this life," then that is also guaranteed. What is that guarantee? Kṛṣṇa says that śucīnāṁ śrīmatāṁ gehe yoga-bhraṣṭo 'bhijāyate (BG 6.41). Yoga-bhraṣṭaḥ, those who cannot fulfill the whole program of Kṛṣṇa consciousness, by some way or other falls down, incomplete. So Kṛṣṇa says, "Such persons are given chance to take birth in the next life in rich family and in pure brāhmaṇa's family." So that means your human life is guaranteed. A rich family does not mean animal family. Rich means human being. And brāhmaṇas means intelligent class of men. So you get your birth in a family where your parents are very intelligent, very advanced in philosophical knowledge, in Kṛṣṇa consciousness. You get chance.
From our practical experience we can say we got this chance. We got this chance. We got very nice parents. And I was born in a family, a very pure family. And, of course, in those days they were rich also. We had Rādhā-Kṛṣṇa mūrti-sevā. So from the childhood I was taught... Not taught. I asked my father, "Give me this Rādhā-Kṛṣṇa mūrti. I shall worship." And father encouraged me. I was performing this Ratha-yātrā festival. My father encouraged. So this means that I got this chance again.
So those who are executing Kṛṣṇa consciousness, they are not in loss. Whatever they are doing, they are gaining some meaning, one percent, two percent, three percent, five percent, ninety-nine percent. It if fulfilled cent percent, then it is perfect. But even it is not cent percent, you are not in a loss because you get good chance to make further advance. These things are discussed. In the Sixth Chapter you will find. So there is guarantee.
