It is not two days' practice. Piano one can practice for twelve years, then it is finished, but this practice you have to do all your life. It is strange, people do not think about simple things. Tell them about occult science, mystic things, they are very pleased. But ordinary things of everyday life, how to live and move among our friends, that is such a difficult thing. It seems to be the easiest. The problem of every moment of life we seem to forget. It must be remembered that during the time of the Summer School, if we continue the practices, attending of the silences, trying one's best to keep one's mind pure from all influences which are poison and having our outgoing sympathetic attitude towards one another, then we shall accomplish work successfully. God Bless You.
