Yogarddhim: here is the speciality of devotees.
Yat-pāda-paṅkaja-parāga-pavitra-dehā: one who is engaged in the service of the lotus feet of the Lord, their body becomes so pure that all the perfection of yoga automatically comes there. Yogarddhim āpur ubhayīṁ. Not only for the next life; in this life also. They are not to be considered as poor and hungry. No. Everything is there, ubhayīṁ. But how? Yat-pāda-paṅkaja-parāga-pavitra-dehā. The paṅkaja, the lotus flower, there is saffron dust. So one who takes shelter of the lotus flower, lotus feet of the Lord, that saffron naturally mixes with this body, so immediately he becomes sanctified. Yogarddhim means "sanctified body." Yoga, so aṇimā, first aṇimā, to make this body light. So practically there is no influence of the body. Just like a dead man becomes heavy. Do you know that? You weigh a living man, and the same man, when he is dead, he becomes heavy. Have you got this experience?
Devotee: No.
Prabhupāda: Yes.
Govinda dāsī: Even when they are sleeping? A sleeping cat.
Prabhupāda: Yes. So the more you become spiritualized, so the material heaviness is diminished. Yat-pāda-paṅkaja-parāga-pavitra-dehā. Now read the translation.
Pradyumna: "The great sage Atri prayed for offspring, and the Lord, being satisfied with him, promised to incarnate as Atri's son, Dattātreya. And by the grace of the lotus feet of the Lord, many Yadus, Haihayas, etc., became so purified that they obtained both material and spiritual blessings."
Prabhupāda: Go on.
Pradyumna: Purport: "Transcendental relations between the Personality of Godhead and the living entities are eternally established in five different affectionate humors, which are known as śānta, dāsya, sakhya, vātsalya and mādhurya. The sage Atri was related with the Lord in the affectionate vātsalya humor, and therefore, as a result of his devotional perfection, he was inclined to have the Personality of Godhead as his son. The Lord accepted his prayer, and He gave Himself as the son of Ātreya."
Prabhupāda: Who can be equal to Him? He wanted, "I want son like You." So where is another person like Him? So He said: "I shall become. I am your son."
Pradyumna: "Such a relation of son-hood between the Lord and His pure devotees can be cited in many instances. And because the Lord is unlimited, He has an unlimited number of father-devotees. Factually, the Lord is the father of all living entities, but out of transcendental affection and love between the Lord and His devotees, the Lord takes more pleasure in becoming the son of a devotee than in becoming one’s father. The father actually serves the son, whereas the son only demands all sorts of services from the father. Therefore a pure devotee . . ."
Prabhupāda: This philosophy is only in Vaiṣṇava philosophy: to accept God as son. In other religions, they accept God as father; but here is a philosophy they accept God as son. Because to accept God as son means to give Him more service. Son takes service from the father: "Give us our daily bread." But the father gives the son daily bread. That is more valuable. If I take from you something, that is not very good; if I give you something, that is good. So to become father of God means to give everything. Even the state, even his money, his bank balance, everything. That is the idea. And to become son of God means to take everything.
