Bhagavad-णॅा  As It Is
[Ch 6]
PURPORTE
Kṛṣṇa is realized in different degrees as Brahman, Paramātmā and the Supreme Personality of Godhead. Kṛṣṇa consciousness means, concisely, to be always engaged in the transcendental loving service of the Lord. But those who are attached to the impersonal Brahman or the localized Supersoul are also partially Kṛṣṇa conscious, because impersonal Brahman is the spiritual ray of Kṛṣṇa and Supersoul is the all-pervading partial expansion of Kṛṣṇa. Thus the impersonalist and the meditator are also indirectly Kṛṣṇa conscious. A directly Kṛṣṇa conscious person is the topmost transcendentalist because such a devotee knows what is meant by Brahman or Paramātmā. His knowledge of the Absolute Truth is perfect, whereas the impersonalist and the meditative  yogī  are imperfectly Kṛṣṇa conscious.
Nevertheless, all of these are instructed herewith to be constantly engaged in their particular pursuits so that they may come to the highest perfection sooner or later. The first business of a transcendentalist is to keep the mind always on Kṛṣṇa. One should always think of Kṛṣṇa and not forget Him even for a moment. Concentration of the mind on the Supreme is called  samādhi , or trance. In order to concentrate the mind, one should always remain in seclusion and avoid disturbance by external objects. He should be very careful to accept favorable and reject unfavorable conditions that affect his realization. And, in perfect determination, he should not hanker after unnecessary material things that entangle him by feelings of possessiveness.
All these perfections and precautions are perfectly executed when one is directly in Kṛṣṇa consciousness because direct Kṛṣṇa consciousness means self-abnegation, wherein there is very little chance for material possessiveness. Śrīla Rūpa Gosvāmī characterizes Kṛṣṇa consciousness in this way:
anāsaktasya viṣayān yathārham upayuñjataḥ 
    nirbandhaḥ kṛṣṇa-sambandhe yuktaṁ vairāgyam ucyate 
    prāpañcikatayā buddhyā hari-sambandhi-vastunaḥ 
    mumukṣubhiḥ parityāgo vairāgyaṁ phalgu kathyate. 
    (Bhakti-rasāmṛta-sindhu 2.255-256)
“When one is not attached to anything, but at the same time accepts everything in relation to Kṛṣṇa, one is rightly situated above possessiveness. On the other hand, one who rejects everything without knowledge of its relationship to Kṛṣṇa is not as complete in his renunciation.”
A) Krşna conscious person well knows that everything belongs to Krşna,
