How activities in Krsna consciousness can lead one ultimately to the spiritual goal is described here. There are various activities in Krsna consciousness, and all of them will be described in the following verses. But, for the present, just the principle of Krsna consciousness is described. A conditioned soul, entangled in material contamination, is sure to act in the material atmosphere, and yet he has to get out of such an environment. The process by which the conditioned soul can get out of the material atmosphere is Krsna consciousness. For example, a patient who is suffering from a disorder of the bowels due to overindulgence in milk products is cured by another milk product, namely curds. The materially absorbed conditioned soul can be cured by Krsna consciousness as set forth here in the Gita. This process is generally known as yajna, or activities (sacrifices) simply meant for the satisfaction of Visnu or Krsna. The more the activities of the material world are performed in Krsna consciousness, or for Visnu only, the more the atmosphere becomes spiritualized by complete absorption. Brahman means spiritual. The Lord is spiritual, and the rays of His transcendental body are called brahmajyoti, His spiritual effulgence. Everything that exists is situated in that brahmajyoti, but when the jyoti is covered by illusion (maya) or sense gratification, it is called material. This material veil can be removed at once by Krsna consciousness; thus the offering for the sake of Krsna consciousness, the consuming agent of such an offering or contribution; the process of consumption, the contributor, and the result are—all combined together—Brahman, or the Absolute Truth. The Absolute Truth covered by maya is called matter. Matter dovetailed for the cause of the Absolute Truth regains its spiritual quality. Krsna consciousness is the process of converting the illusory consciousness into Brahman, or the Supreme. When the mind is fully absorbed in Krsna consciousness, it is said to be in samadhi, or trance. Anything done in such transcendental consciousness is called yajna, or sacrifice for the Absolute. In that condition of spiritual consciousness, the contributor, the contribution, the consumption, the performer or leader of the performance, and the result or ultimate gain—everything—becomes one in the Absolute, the Supreme Brahman. That is the method of Krsna consciousness.
