Śrīmad-Bhāgavatam
[Canto 3, Ch. 33]
means cessation of the materialistic way of life.  Ātmānam  means realization of the Supersoul within the heart. Ultimately, the highest perfection is realization of the Supreme Personality of Godhead. It is to be understood that Devahūti entered the planet which is called Kapila Vaikuṇṭha. There are innumerable Vaikuṇṭha planets predominated by the expansions of Viṣṇu. All the Vaikuṇṭha planets are known by a particular name of Viṣṇu. As we understand from  Brahma-saṁhitā ,  advaitam acyutam anādim ananta-rūpam .  Ananta  means innumerable. The Lord has innumerable expansions of His transcendental form, and according to the different positions of the symbolical representations in His four hands, He is known as Nārāyaṇa, Pradyumna, Aniruddha, Vāsudeva, etc. There is also a Vaikuṇṭha planet known as Kapila Vaikuṇṭha, to which Devahūti was promoted to meet Kapila and reside there eternally, enjoying the company of her transcendental son.
