Śrīla Bhaktisiddhānta Saraswatī Ṭhākur once instructed a disciple at the time of initiation into the Hare Krishna mantra that Krishna should be allowed to land in our hearts, just as an army is landed by the navy. An army is carried by a ship, and when they have landed, the fight begins, and they capture the country, just as Julius Caesar said, “Veni vidi vici, I came, I saw, I conquered.” So, we have to allow Krishna to land in our hearts. Then the fight will begin.
What is the proposal of Krishna consciousness, and what is the proposal of so many other conceptions? They are all giving us their assurances from time immemorial, saying, “I shall give you this, I shall give you that,” but the Krishna conception will enter and say, “My claim is this: the whole thing is Mine, and you are all trespassers.” The fight will begin; the unwanted things are sure to withdraw, and Krishna consciousness will capture the whole heart. This is the process. Krishna consciousness has only to land within our hearts. Somehow or other, from a pure devotee, a bit of real Krishna consciousness should enter through our ears into our hearts, and Krishna will supply whatever is required. One who has imbibed even a slight regard for Krishna consciousness is assured of success in spiritual life, today or tomorrow.
