In the conditioned stage there is every possibility of being mistaken; but Krishna will always protect us if we are sincere; even if there is a gross mistake, Krishna forgives his devotee who is very sincere; so go on working sincerely and Krishna will protect you always.
Correspondence, Vrindavan, August 1967

We should always remember that Krishna is the only order giver. His order is received through the agency of the spiritual master. The bona fide spiritual master is the manifest representative of Krishna. The spiritual master is described in the scriptures as good as Krishna because he is the most confidential servitor of Krishna. To please the spiritual master is to please Krishna.

The only means of protecting ourselves from the attack of maya is to be fully Krishna Conscious. The proportion in which we fall back in Krishna Consciousness is filled up by the influence of maya. It is exactly like the proportion of negligence of our health is subsequently resulted in our falling ill.

As a man haunted by a ghost talks so much nonsense, so also when a man is overpowered by the illusory energy—maya, also talks all sorts of nonsense. The last attack of maya upon the conditioned souls is impersonalism. There are 4 stages of attack of maya; viz.: 1) stage is that a man wants to be a protagonist of religion, 2) is that man neglects religiosity and tries to improve his economic development, 3) is to be protagonist of sense enjoyment & when a man is frustrated in all the above mentioned stages he comes to, 4) which is impersonalism, and thinks himself one with the Supreme. This last attack is very serious and fatal.

The Lord remains in the hearts of every living entity. He lives in the heart of a hog, and the hog lives in a filthy place. That does not mean that the Lord lives in a filthy place. The Lord lives always inconceivably in His transcendental abode. Similarly, a fully Krishna Conscious person lives always in the pastimes of Lord Krishna by such consciousness only. The material atmosphere is no impediment for continuing our Krishna Consciousness in any circumstance.
