In the Bhagavad-gita, it is said that even a very small attempt in the path of Krishna Consciousness can save one from the greatest danger. Krishna Consciousness is spiritual consciousness, and whatever is achieved in the matter of realization of this spiritual progress, will never go in vain. The fact is that there are two kinds of consciousness: Krishna Consciousness, and non-Krishna Consciousness. A man may perform Krishna Consciousness to a certain percentage, and another man may perform Krishna Consciousness to greater percentage or cent per cent progress.
