Best achievement of life is the how to stop this getting material body again. Spiritual body, that is happiness. Then you will get eternal happiness, blissful life. Tyaktvā dehaṁ punar janma naiti mām eti kaunteya (BG 4.9). That you go to the spiritual world. There is spiritual world, as this, here, is material world, you have got material body. So if you are fit for going to the spiritual world, then you'll get spiritual body, same way. And spiritual body means sac-cid-ānanda-vigraha (Bs. 5.1), spiritual body. Vigraha means body, and sac-cid-ānanda. . . Sat means eternal, cit means full of knowledge, and ānanda, blissful. That we want. The Kṛṣṇa consciousness movement means to try to understand Kṛṣṇa. Very easy. If you drink water as Kṛṣṇa advises, raso 'ham apsu kaunteya. That satisfaction by drinking water, that is Kṛṣṇa. That's all. You think, "This is Kṛṣṇa." You think that "I am drinking Kṛṣṇa." Then twice, thrice "Kṛṣṇa" means you become purified. Kṛṣṇa. . . Eka kṛṣṇa-nāme yato pāpa hare, pāpī haya tato pāpa kari bare nare(?). Eka kṛṣṇa, one, once chanting of Kṛṣṇa, it can kill so many reaction of sinful life that you cannot do so many sinful life. A sinful man can do large amount of sinful activities. But you cannot do even.
So this process, if you adopt. . . Very easy. It is authenticated. We have not manufactured this. It is said in the Bhagavad-gītā, raso 'ham apsu kaunteya (BG 7.8), "That rasa, that satisfaction by drinking water, that is I am." So why not think of Kṛṣṇa like that? You drink so many times water, especially in India. Hey? You drink water and think of Kṛṣṇa, you become perfect.
