The Lord is all-pervading. As it is stated by Lord Kṛṣṇa in the Bhagavad-gītā, “Everything is sustained by Me, but at the same time I am not in everything.” Since the Lord is all-pervading, there is nothing existing without His knowledge. The all-pervasive nature of the Supreme Personality of Godhead can never be within the limited knowledge of a living entity; therefore, a person who has attained steadiness of the mind by fixing the mind on the lotus feet of the Lord is able to understand the Supreme Lord to some extent. It is the business of the mind to wander over varied subject matter for sense gratification. Therefore only a person who always engages the senses in the service of the Lord can control the mind and be fixed at the lotus feet of the Lord. This concentration of the mind upon the lotus feet of the Lord is called samādhi. Until one reaches the stage of samādhi, or trance, he cannot understand the nature of the Supreme Personality of Godhead. There may be some philosophers or scientists who can study the cosmic nature from atom to atom; they may be so advanced that they can count the atomic composition of the cosmic atmosphere or all the planets and stars in the sky, or even the shining molecular particles of the sun or of the stars and other luminaries in the sky. But it is not possible to count the qualities of the Supreme Personality of Godhead.
As described in the beginning of the Vedānta-sūtra, the Supreme Person is the origin of all qualities. He is generally called nirguṇa. Nirguṇa means “whose qualities are beyond estimation.” Guṇa means “quality,” and nir means “beyond estimation.” But impersonalists interpret this word nirguṇa as “having no quality.” Because they are unable to estimate the qualities of the Lord in transcendental realization, they conclude that the Supreme Lord has no qualities. But that is actually not the position. The real position is that He is the original source of all qualities. All qualities are emanating constantly from Him. How, therefore, can a limited person count the qualities of the Lord? One may estimate the qualities of the Lord at one moment, but the next moment the qualities have increased; so it is not possible to make an estimation of the transcendental qualities of the Lord. He is therefore called nirguṇa, one whose qualities cannot be estimated.
One should not uselessly labor in mental speculation to estimate the Lord’s qualities. There is no need of adopting the speculative method or exercising the body to attain mystic yoga perfection. One should simply understand that the distress and happiness of this body are predestined; there is no need to try to avoid the distress of this bodily existence or to attempt to achieve happiness by different types of exercises. The best course is to surrender unto the Supreme Personality of Godhead with body, mind and words and always be engaged in His service. This transcendental labor is fruitful, but other attempts to understand the Absolute Truth are never successful. Therefore an intelligent man does not try to understand the Absolute Truth by speculative or mystic power. Rather, he engages in devotional service and depends on the Supreme Personality of Godhead. He knows that whatever may happen to the body is due to his past fruitive activities. If one lives such a simple life in devotional service, then automatically he inherits the transcendental abode of the Lord. Actually, every living entity is part and parcel of the Supreme Lord and a son of the Godhead. Each has the natural right to inherit and share the transcendental pleasures of the Lord, but due to the contact of matter, conditioned living entities have been practically disinherited. If one adopts the simple method of engaging himself in devotional service, automatically he becomes eligible to be freed from material contamination and elevated to the transcendental position of associating with the Supreme Lord.
