“The atmosphere today is polluted by bad thoughts and feelings. When you sing the glory of God, the bad germs in the air are destroyed and the air gets purified by a treatment with anti-biotics as it were.”

…Sathya Sai Baba,  “Chant the Name sing His glory”  Discourse, Trayee Brindavan, 23-10-1994     https://www.sssbpt.info/ssspeaks/volume27/sss27-29.pdf

“Among the nine steps of devotional progress, the fourth and the fifth highlight the attitude of seva; it is referred to as Padasevanam and Dasyam (serving the Feet of the Lord; acts offered at the Feet of the Lord; feeling oneself as the servant of the Lord). Service is basically activity arising out of the yearning to win the Grace of God. Through seva alone can man attain Mastery, and through mastery of the senses, passions and the predilections, man can attain Divinity itself. “
