"Everyone wants to love. That is natural propensity. Everyone. When there is no loving object, then in this material world we sometimes love cats and dogs. You see? Because I must love somebody. If I don't find any suitable person lovable, then I turn my love to some hobby, to some animal, like that, because the love is there. So this is dormant. Our love for Kṛṣṇa is dormant. It is within us, but because we have no information of Kṛṣṇa, therefore we are reposing our love to something which is frustration. That is not the object of love. Therefore we are frustrated. So many instances we have got, we did not describe. But here in this material world, love is 99.9% all frustration, because the love is not reposed to the proper place. The proper place is Kṛṣṇa. If we love Kṛṣṇa, then we can love everyone. Just like if we pour water on the root of the tree then the other parts of the tree, leaves and flowers and fruits and branches, automatically... So if we learn to love Kṛṣṇa, then we can perfectly love others.
So those who are eternally liberated, they love Kṛṣṇa. Therefore they are perfect in the spiritual world. 'Nitya-mukta'-nitya kṛṣṇa-caraṇe unmukha, 'kṛṣṇa-pāriṣada' nāma. They are all associates. The Supreme Lord is person, and His innumerable lovers, living entities, they are also individual persons. Love means there is person, individual. Without individual person, there is no question of love. When I, when the word 'love' is used, there must be two lovers. Then the word is applicable, love. If there is no person, love is not with the air. There must be person. So the Supreme Lord is person, and the lovers, the living entities, they are also persons. They forget who is God, who is not God, but the central focus is in Kṛṣṇa. Everyone loves Kṛṣṇa. Without seeing Kṛṣṇa they are mad. This is the position in the spiritual world. Simply love Kṛṣṇa, that's all. Bhuñje sevā-sukha. And by loving, as we have got a little perverted experience of love affairs, so just imagine when that love is pure and true, how much pleasure there is. So that thing is there in the spiritual world, pure love. And object is Kṛṣṇa. Therefore they are so much in bliss... that is bliss, that is bliss. Sac-cid-ānanda-vigrahaḥ, eternal love with knowledge that 'Here is Kṛṣṇa,' and ānandamayo 'bhyāsāt. That is perfect stage, lovable object eternal, lover eternal, with knowledge, with eternal life. That is there. In the spiritual world this is going on. They're all in bliss."
