To drink pure water from a shallow pond one should gently take the water from the surface without disturbing the pond in the least. If it is disturbed, the sediments rise up and make the whole water muddy. If you desire to be pure, have firm faith, and slowly go on with your devotional practices, without wasting your energy in useless scriptural discussions and arguments. Your little brain will otherwise be muddled.
Many are the men who study scriptures and talk of religion, but very few are those who wish to see God or take pains to approach Him.
