What is Krishna Consciousness?
Krishna consciousness, or bhakti-yoga, means how to act in harmony with ultimate reality - the Supreme Person. Bhakti - "devotional service" - is how the Bhakta - "devotee" - and Bhagvan - "God, the possessor of all opulence"-relate.
We're all naturally Krishna conscious. In illusion, we think we're the center of the universe, and our bodies are our real selves. Krishna consciousness means becoming free from that illusion, and experiencing our true blissful, eternal nature.
It's a process that works. Anyone can do it. Krishna consciousness is both a "practise" and the goal of the practice. The goal is to be Krishna conscious. The practice is to always stay conscious of Krishna.
