“I have directed that you should start the day with Nagar Sankeertan (street singing of spiritual hymns), for, it is the greatest disinfectant of the atmosphere of the individual, as well as the community. The puja (ritualistic worship) in the domestic shrine, the recitation of hymns, the bhajan (group singing of devotional songs) that you do, all send forth vibrations that purify and cleanse the atmosphere, and so, disinfect the 'food' that you consume.”

“It is the weak, the destitute, and the helpless who need to be served. Even in rendering service to such persons, there should be no feeling that we are serving 'others'. We should feel that we are serving the Lord Narayana who dwells in them. When service is rendered in a total spirit of dedication, with concentration of thought, word, and deed, the heart gets sanctified. Without purity of the heart there can be no spiritual progress.”
