Guest (2): ...by working towards perfection in my duty...
Prabhupāda: Yes, that perfection is to please Kṛṣṇa. If by... You are doing everything. That's all right, but if by your working Kṛṣṇa is satisfied, then that working is perfect. If Kṛṣṇa is not satisfied, then it is useless, waste of time.
Guest (2): But how do I come to know that Kṛṣṇa is satisfied?
Prabhupāda: That you have to learn by Kṛṣṇa consciousness. By becoming... Just like Kṛṣṇa says, whatever Kṛṣṇa says, you have to do that. Kṛṣṇa says, man-manā bhava mad-bhakto mad-yājī māṁ namaskuru: (BG 18.65) "Always think of Me, become My devotee, offer your obeisances unto Me." Man-manā bhava. "Become My devotee." So if you abide by this, then Kṛṣṇa is satisfied. Kṛṣṇa says, yat karoṣi yaj juhoṣi yad aśnāsi yat tapasyasi kuruṣva tad mad-arpaṇam: (BG 9.27) "Whatever you are doing, it doesn't matter, but you do it for Me."
Guest (2): Without any selfish interest.
Prabhupāda: Yes. You remain servant of Kṛṣṇa. Just like a servant discharges his duty very faithfully for the satisfaction of the master, similarly, you have got industry, if you work in this industrial work for the satisfaction of Kṛṣṇa... Just like this boy behind you, he is working somewhere, getting good salary. But I had told him that "some percentage you must give to Kṛṣṇa." He is regularly giving.
Guest (2): If I feel I have love for Kṛṣṇa, is that enough to be a devotee.
Prabhupāda: But you must show how your love... Simply if you say... Suppose, anywhere in this material world, if you say somebody that "I love you," but there is no symptoms of love, then what kind of love? Love symptoms means dadāti, giving. First symptom. Just like when a boy goes to love a girl, he brings something. That is ordinary etiquette. So first beginning of love is dadāti, pratigṛhṇāti. If I love you, I must give you. And if you offer me, I will take it, I will take something. Pratigṛhṇāti. Exchange, giving and taking. Dadāti pratigṛhṇāti, bhuṅkte bhojayate. If you love somebody, give him to eat, and whatever he gives you, you also eat. Dadāti pratigṛhṇāti bhuṅkte bhojayate, guhyam ākhyāti pṛcchati. And if you love somebody then you disclose your mind to him and try to understand him also. By these six processes the symptoms of love is there. But if you say that "I love you," but there is no action...
Guest (2): That giving should be without any intention of taking.
Prabhupāda: No, no profit making, no business that "I give you something. I must have something from you." No, no. Love means without any desire, anyābhilāṣitā-śūnyam (Brs. 1.1.11), without any motive. That is pure love. If I give you something without any motive, that is pure love.
