You'll find in the Bhagavad-gītā that śucīnāṁ śrīmatāṁ gehe yoga-bhraṣṭo 'bhijāyate (BG 6.41). This is called bhakti-yoga. Suppose somebody is enjoying, but māyā is very strong. If he falls down... He could not execute the Kṛṣṇa consciousness program completely in this life. Mostly if you simply stick, there is no difficulty. But if voluntarily we give up, that is another thing. What is the wrong there? Chant, dance, and take prasādam. You haven't got to work. You haven't got to go to the field work or to the factory. Still, if you don't accept it—you fall down—so that is your choice. But even if you fall down, because for a few days you joined Kṛṣṇa consciousness movement, your the resultant actions for so much time is permanent asset. Permanent asset. What is that permanent asset? That is stated in the Bhagavad-gītā, that śucīnāṁ śrīmatāṁ gehe yoga-bhraṣṭo 'bhijāyate. Those who have fallen from this Kṛṣṇa consciousness, their next life is guaranteed a human life.
Because others, there is no guarantee. Tathā dehāntara-prāptiḥ (BG 2.13). According to one's karma he can get the body of a dog, cat, hog or demigod. There is no guarantee that... Kṛṣṇa says, tathā dehāntara-prāptiḥ. Antara means another. He does not say that "This body he'll get." But if one is Kṛṣṇa's devotee, then there is guarantee. What is that guarantee? Śucīnāṁ śrīmatāṁ gehe (BG 6.41). He'll take birth in a very rich family or in a very nice brāhmaṇa and Vaiṣṇava's family. If he gets a Vaiṣṇava's, birth in a Vaiṣṇava's family... Just like we have got so many children among our gṛhastha devotees. How fine they are. They're getting Kṛṣṇa consciousness from the beginning of their life. That means in the past they advanced in Kṛṣṇa consciousness. Somehow or other they failed to complete. Now they have got again chance, again in the temple, dancing and chanting from the very beginning of life.
So this is the opportunity. So this knowledge, rāja-vidyā rāja-guhyaṁ pratyakṣāvagamaṁ dharmyam, susukhaṁ kartum avyayam (BG 9.2). Avyayam means in ordinary fruitive activities whatever you do... Suppose by karma, by material activities, fruitive activities, you become very rich man or very learned man, very good office. But everything will be finished with your death. As soon as the body is finished, all your asset finished. But if you become a devotee, your body may be finished but the soul is eternal. The soul will carry your assets of Kṛṣṇa consciousness, and nature will give you another chance of taking birth in a very rich family or in a Vaiṣṇava family. To get birth in a Vaiṣṇava family is greater asset than to take birth in rich family. Rich family means there is no economic problem. But on account of richness one may fall down, but if one takes birth in a Vaiṣṇava family there is no more fall down. He makes progress further and further. In this way he is allowed again go back to home, back to Godhead.
