SB Canto 4

Therefore vasudeva also means kaivalya, a word which is generally used by impersonalists. Impersonal kaivalya is not the last stage of realization, but in Kṛṣṇa consciousness kaivalya, when one understands the Supreme Personality of Godhead, then one is successful. In that pure state, by hearing, chanting, remembering, etc., because of the development of knowledge of the science of Kṛṣṇa, one can understand the Supreme Personality of Godhead. All these activities are under the guidance of the internal energy of the Supreme Lord.

SB 4.3.23, Purport:

Therefore śuddha-sattva, as described in this verse, is the transcendental position, which is technically called vasudeva. Vasudeva is also the name of the person from whom Kṛṣṇa appears. This verse explains that the pure state is called vasudeva because in that state Vāsudeva, the Supreme Personality of Godhead, is revealed without any covering. To execute unadulterated devotional service, therefore, one must follow the rules and regulations of devotional service without desire to gain material profit by fruitive activities or mental speculation.

In pure devotional service one simply serves the Supreme Personality of Godhead as a matter of duty, without reason and without being impeded by material conditions. That is called śuddha-sattva, or vasudeva, because in that stage the Supreme Person, Kṛṣṇa, is revealed in the heart of the devotee. Śrīla Jīva Gosvāmī has very nicely described this vasudeva, or śuddha-sattva, in his Bhagavat-sandarbha. He explains that aṣṭottara-śata (108) is added to the name of the spiritual master to indicate one who is situated in śuddha-sattva, or in the transcendental state of vasudeva. The word vasudeva is also used for other purposes. For example, vasudeva also means one who is everywhere, or all-pervading. The sun is also called vasudeva-śabditam. The word vasudeva may be utilized for different purposes, but whatever purpose we adopt, Vāsudeva means the all-pervading or localized Supreme Personality of Godhead. In Bhagavad-gītā (7.19) it is also stated, vāsudevaḥ sarvam iti. Factual realization is to understand Vāsudeva, the Supreme Personality of Godhead, and surrender unto Him. Vasudeva is the ground wherein Vāsudeva, the Supreme Personality of Godhead, is revealed. When one is free from the contamination of material nature and is situated in pure Kṛṣṇa consciousness, or in the vasudeva state, Vāsudeva, the Supreme Person, is revealed. This state is also called kaivalya, which means "pure consciousness." Jñānaṁ sāttvikaṁ kaivalyam. When one is situated in pure, transcendental knowledge, one is situated in kaivalya. Therefore vasudeva also means kaivalya, a word which is generally used by impersonalists. Impersonal kaivalya is not the last stage of realization, but in Kṛṣṇa consciousness kaivalya, when one understands the Supreme Personality of Godhead, then one is successful. In that pure state, by hearing, chanting, remembering, etc., because of the development of knowledge of the science of Kṛṣṇa, one can understand the Supreme Personality of Godhead. All these activities are under the guidance of the internal energy of the Supreme Lord.

The action of the internal potency is also described in this verse as apāvṛtaḥ, free from any covering. Because the Supreme Personality of Godhead, His name, His form, His quality, His paraphernalia, etc., being transcendental, are beyond material nature, it is not possible to understand any one of them with the materialistic senses. When the senses are purified by the discharge of pure devotional service (hṛṣīkeṇa hṛṣīkeśa-sevanaṁ bhaktir ucyate (CC Madhya 19.170)), the pure senses can see Kṛṣṇa without covering. Now one may inquire that since factually the devotee has the same material existential body, how is it possible that the same materialistic eyes become purified by devotional service? The example, as stated by Lord Caitanya, is that devotional service cleanses the mirror of the mind. In a clean mirror one can see one's face very distinctly. Similarly, simply by cleansing the mirror of the mind one can have a clear conception of the Supreme Personality of Godhead. It is stated in Bhagavad-gītā (8.8), abhyāsa-yoga-yuktena. By executing one's prescribed duties in devotional service, cetasā nānya-gāminā, or simply by hearing about God and chanting about Him, if one's mind is always engaged in chanting and hearing and is not allowed to go elsewhere, one can realize the Supreme Personality of Godhead. As confirmed by Lord Caitanya, by the bhakti-yoga process, beginning from hearing and chanting, one can cleanse the heart and mind, and thus one can clearly see the face of the Supreme Personality of Godhead.
