SB 4.3.23
sattvam visuddham vasudeva-sabditam
yad iyate tatra puman apavrtah
sattve ca tasmin bhagavan vasudevo
hy adhoksajo me namasa vidhiyate
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
I am always engaged in offering obeisances to Lord Vasudeva in pure Krsna consciousness. Krsna consciousness is always pure consciousness, in which the Supreme Personality of Godhead, known as Vasudeva, is revealed without any covering.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The living entity is constitutionally pure. Asango hy ayam purusah. In the Vedic literature it is said that the soul is always pure and uncontaminated by material attachment. The identification of the body with the soul is due to misunderstanding. As soon as one is fully Krsna conscious it is to be understood that one is in his pure, original constitutional position. This state of existence is called suddha-sattva, which means that it is transcendental to the material qualities. Since this suddha-sattva existence is under the direct action of the internal potency, in this state the activities of material consciousness stop. For example, when iron is put into a fire, it becomes warm, and when red-hot, although it is iron, it acts like fire. Similarly, when copper is surcharged with electricity, its action as copper stops; it acts as electricity. Bhagavad-gita (14.26) also confirms that anyone who engages in unadulterated devotional service to the Lord is at once elevated to the position of pure Brahman:
mam ca yo ’vyabhicarena
bhakti-yogena sevate
sa gunan samatityaitan
brahma-bhuyaya kalpate
Therefore suddha-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 Krsna appears. This verse explains that the pure state is called vasudeva because in that state Vasudeva, 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 suddha-sattva, or vasudeva, because in that stage the Supreme Person, Krsna, is revealed in the heart of the devotee. Srila Jiva Gosvami has very nicely described this vasudeva, or suddha-sattva, in his Bhagavat-sandarbha. He explains that astottara-sata (108) is added to the name of the spiritual master to indicate one who is situated in suddha-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-sabditam. The word vasudeva may be utilized for different purposes, but whatever purpose we adopt, Vasudeva means the all-pervading or localized Supreme Personality of Godhead. In Bhagavad-gita (7.19) it is also stated, vasudevah sarvam iti. Factual realization is to understand Vasudeva, the Supreme Personality of Godhead, and surrender unto Him. Vasudeva is the ground wherein Vasudeva, the Supreme Personality of Godhead, is revealed. When one is free from the contamination of material nature and is situated in pure Krsna consciousness, or in the vasudeva state, Vasudeva, the Supreme Person, is revealed. This state is also called kaivalya, which means “pure consciousness.” Jñanam sattvikam 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. In Krsna 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 Krsna, 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 apavrtah, 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 (hrsikena hrsikesa-sevanam bhaktir ucyate), the pure senses can see Krsna 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-gita (8.8), abhyasa-yoga-yuktena. By executing one’s prescribed duties in devotional service, cetasa nanya-gamina, 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.
Lord Siva said that since his heart was always filled with the conception of Vasudeva, the Supreme Personality of Godhead, because of the Supreme Lord’s presence within his mind and heart, he was always offering obeisances unto that Supreme Godhead. In other words, Lord Siva is always in trance, samadhi. This samadhi is not under the control of the devotee; it is under the control of Vasudeva, for the entire internal energy of the Supreme Personality of Godhead acts under His order. Of course, the material energy also acts by His order, but His direct will is specifically executed through the spiritual energy. Thus by His spiritual energy He reveals Himself. It is stated in Bhagavad-gita (4.6), sambhavamy atma-mayaya. Atma-mayaya means “internal potency.” By His sweet will He reveals Himself by His internal potency, being satisfied by the transcendental loving service of the devotee. The devotee never commands, “My dear Lord, please come here so that I can see You.” It is not the position of the devotee to command the Supreme Personality of Godhead to come before him or to dance before him. There are many so-called devotees who command the Lord to come before them dancing. The Lord, however, is not subject to anyone’s command, but if He is satisfied by one’s pure devotional activities, He reveals Himself. Therefore a meaningful word in this verse is adhoksaja, for it indicates that the activities of our material senses will fail to realize the Supreme Personality of Godhead. One cannot realize the Supreme Personality of Godhead simply by the attempt of one’s speculative mind, but if one desires he can subdue all the material activities of his senses, and the Lord, by manifesting His spiritual energy, can reveal Himself to the pure devotee. When the Supreme Personality of Godhead reveals Himself to the pure devotee, the devotee has no other duty than to offer Him respectful obeisances. The Absolute Truth reveals Himself to the devotee in His form. He is not formless. Vasudeva is not formless, for it is stated in this verse that as soon as the Lord reveals Himself, the devotee offers his obeisances. Obeisances are offered to a person, not to anything impersonal. One should not accept the Mayavada interpretation that Vasudeva is impersonal. As stated in Bhagavad-gita, prapadyate: one surrenders. One surrenders to a person, not to impersonal nonduality. Whenever there is a question of surrendering or offering obeisances, there must be an object of surrender or obeisances.
