Water is very clean. When it rains from the clouds it is very clean, but as soon as it drops on the ground it becomes muddy. So that muddiness has to be cleansed then water will come out again clean. Similarly, our consciousness is clean, but because it is contaminated with the muddy things of the material nature, it is cloudy.
We can get rid of the impurities of the heart by turning our consciousness towards Krishna. With mind we can think of Krishna and project our consciousness towards Him.
Maya is so thorough, just like water, if there's one little hole, the water wil just find its way immediately to that hole. And the problem is our consciousness has so many holes.
Simply performing devotional activities will not impart devotion to others but our consciousness should be absorbed.
Consciousness is important… Killer says, "I Shall kill you." Surgeon says, "I shall save you."
