When dirty water gets mixed with milk, the milk has to be boiled to make it pure. Likewise man has to undertake various types of Sadhana to purge his heart of impurities. Exercises such as meditation, chanting, etc. can only provide mental satisfaction. It is only when the heart is melted in the heat of Divine love that one can succeed in getting rid of bad qualities and make the heart shine in its pristine effulgence. Just as the sun's rays can burn a heap of cotton if the rays are concentrated by passing through a lens, the rays of the intellect will destroy one's bad qualities only when they are passed through the lens of Divine love.
