I am in due receipt of your letter of February 7, 1969, and I have carefully noted the contents. I have also seen the leaflets done by this boy, Mark, and they are very nicely done. Regarding your question about the 10 senses, such questions should be taken up at your Istagosthi meetings. I have already answered most of the questions you have asked in this connection in a previous letter, so you may refer to it.
About the shell which you are presently keeping in the temple, because it is not a conchshell, it should be considered as impure, and therefore it may not be placed upon the altar. Regarding the meter sung by Narada Muni, it is not necessary for us to practice this. For your final question, you are correct in your idea that leaflets which are destined to be thrown upon the ground should not contain pictures of Krishna, Jagannatha, etc. Such leaflets may only be hung up for people to see.
