Kṛṣṇa advises, man-manā bhava mad-bhakto. Man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65), mām evaiṣyasi asaṁśayam. Asaṁśayam, "without any doubt." If you want to go back to home, back to Godhead, which is known as Kṛṣṇaloka, Vaikuṇṭhaloka. . . Vaikuṇṭhaloka means. . . Kuṇṭha means this anxiety, and vaikuṇṭha. . . Vigata-kuṇṭha. Vigata means without. There is no more any anxiety. That is Vaikuṇṭhaloka, spiritual world. Material world is kuṇṭha. Kuṇṭha means anxiety, full of anxiety, and Vaikuṇṭha means there is no anxiety; everything is freedom, sac-cid-ānanda. Vaikuṇṭha life means sac-cid-ānanda. Kṛṣṇa's body is sac-cid-ānanda-vigrahaḥ (Bs. 5.1). Not only Kṛṣṇa's body; anyone who lives in the spiritual world, his body is spiritual body, and spiritual body means sat, cit, ānanda. Sat means eternal. Spiritual body never annihilates. The material body annihilates. Every one of us, we have got now material body. It will annihilate. But in the spiritual world, when you have got spiritual body, it does not annihilate. Eternal. Eternal life. And cit means knowledge. So in this material body we have no knowledge. Even if we have got. . ., now imperfect knowledge, limited knowledge. But in the spiritual life you have got full knowledge. That is spiritual life.
And ānanda. Here is no ānanda. In this material world. . . Ānanda means pleasure, bliss. But here it is not possible. First of all, you have to die. You may manufacture some so-called ānanda, but you'll die. Now, suppose we are dancing here, and if we understand that immediately death will take place, then we shall not be able to enjoy the dancing. Immediately the anxiety will come. So here, ānanda, there is no ānanda. Why there is ānanda? This body is subjected to so many miserable condition of life. We become hungry, we become thirsty, there is death, there is fearfulness, there is enemy—so many things. If you study analytically that this body is simply meant for suffering, so where is ānanda? There is no ānanda; there is no complete knowledge; there is no eternity. Therefore it is called material. Just the opposite is spiritual life. Just opposite. There is no death—eternity. So civilization means that the process by which we can transfer ourself from this nonpermanent life to permanent life, life of ignorance to life of knowledge, life of suffering to life of enjoyment. That is spiritual life.
