Kṛṣṇa says there are four kinds of beginners of devotional service. Four kinds. What are . . . who are they? Ārtaḥ. Ārtaḥ means one who is distressed; artha-arthī, one who is in want of money; ārto ar . . . jijñāsuḥ, one who is searching after knowledge; and jñānī, and wise man. So out of these, ārto and arthārthī, they are low-grade worshiper. Those who are jñānī and jijñāsuḥ, they are higher grade. Generally, they are lower grade. But they are not pure devotee.
Pure devotees, as we have explained yesterday, they do not want anything from God. Even liberation they do not want, what to speak of this material . . . therefore the philosophy of becoming the father of Kṛṣṇa is very perfect. Because one hasn't got to ask, like the son asks from the father, "Father, give me this, give me this." Because devotee want . . . doesn't want to ask anything from. Then how he can become son? Son business is to ask from father. Therefore they do not aspire to become the son of Godhead, but they aspire to be father of Godhead. This is perfection—Nanda Mahārāja, father; Vasudeva, father. Kṛṣṇa will always ask. Just like Kṛṣṇa is always asking to suck the breast of Mother Yaśodā. Always demanding. And if she refuses, she'll (He'll) create disturbance. And Mother Yaśodā is always thinking that "If I do not feed Kṛṣṇa nicely, He'll die." This is love. This is love. Therefore it is said that yeṣām ahaṁ priya ātmā sutaś ca. The devotee accept Kṛṣṇa as suta, as son, not as father. Father means exacting.
So in this way, if we actually establish . . . establish means reestablish. It is already established. We have got different types of relationship. That is called svarūpa-siddhi. Svarūpa-siddhi. When you are perfect in spiritual life, you will understand what is your relationship with Kṛṣṇa automatically. That is called svarūpa-siddhi. You have got original relationship with Kṛṣṇa. Nitya-siddha kṛṣṇa-bhakti, Caitanya-caritāmṛta. That is a . . . just like you are son of some gentleman. That is a fact. It is not that the son becomes father or the father becomes son. No. The son is son; the father is father. Similarly, we have got an eternal relationship with Kṛṣṇa, either as father, or as lover, or as servant, like that. So that is self-realization. When you will be perfect in love, in loving Kṛṣṇa, then in what status of life you will love, that you will under . . . that will be revealed. That is called svarūpa-siddhi. So svarūpa-siddhi is not something artificial. When one becomes perfectly spiritually realized, then he understands what is his relationship with Kṛṣṇa and he begins his service in that relationship as father, as friend, as guru or as servant, like that.
So this relationship is eternal. So instead of being attached to this temporary relationship . . . somebody thinking that, "I have to serve my father and mother. That is my first duty." That's all right. First of all you select who is your father and mother. Now you have got a certain living entity as your father. Again, as you change body, your father may be somebody else. Today you have got a father human being, and tomorrow you may have a father who may not be human being. You have to accept a dog as your father, or a cat as your father. So your father is changing with the change of your body. So first of all select who is your father. This dog is your father? The man is your father? The cat is your father? Who is your father? The tree is here, the seed is your father? Then you become devotee of father. But that we cannot do. Therefore Kṛṣṇa said, sarva-dharmān parityajya mām ekaṁ śaraṇam (BG 18.66): "You accept Me as your son, as your friend, as your master. Then you will be happy."
