Regarding that man Cinmayananda, he's a sinful man, I know him, at least sinful according to our four principles. He as been lecturing for 20 years, still his asrama stands vacant. Unless one's life is made up, what this lecturing will do?
So far your other letter, devotion does not depend on the body, and in spite of all difficulties we can chant, so long we have got the tongue—and even we have got no tongue we can chant in our mind. So where is the question of not serving with devotion? On the contrary, I consider that you and your good husband, Gaurasundara, are two of my topmost disciples and the work you are doing greatly encourages and pleases me, therefore do not think that because you are sometimes sick or weak that you are not making any advancement and that you are disappointing me, no. I am always thinking upon you both, that Krishna will give you His all blessings. Simply if you are able always to chant Hare Krishna, that is the same as following all other regulative principles.
