Krsna consciousness is a great mystery for many people. Some have spent a life searching and researching, analyzing every word of the Vedas, looking under every rock, tolerating the ups and downs-heat and cold- food-no food like the yogis and they still don't have a clue of the reality that is Krsna. Some have described it as love of God others have defined it as God Consciousness, Divine Love and of course the dull headed Atheist refer to it as Sentiment or Fanaticism. In any event it is stated in the Sri Isopanisad that one may travel at the speed of mind for hundreds and thousands of years and still not get a glimpse of the absolute reality.
When one gives up the egotistic idea that he can capture Krsna by his own intellectual effort or sensual discipline and admit from the core of his heart that Krsna is one's true benefactor and fully depend on him, by agreeing to be humble and serve the Divine Nama, Krsna being the most merciful will lovingly reveal himself to the devoted soul by the sound vibration produced from his representative (The Genuine Spiritual Master) .
Some have addressed Krsna as Allah, Jehovah, God and so on, all of which are based on local custom and language. The Name Krsna however when fully realized is understood to contain all the transcendental qualities that his other names attempt to describe.
Sabda brahma is present in the lord's holy name when heard from the lips of his pure devotees. Lord Caitanya has said that the supreme lord has invested all his transcendental potency's in the Maha Mantra, the Great Mantra of Deliverance. - AJD
