My dear Vasudeva, you and your good wife Devakī have manifested great transcendental love for Kṛṣṇa, accepting Him as your son. Indeed, you are always seeing the Lord, embracing Him, speaking with Him, resting with Him, sitting together with Him and taking your meals with Him. By such affectionate and intimate association with the Lord, undoubtedly both of you have completely purified your hearts. In other words, you are already perfect.
