Any religious act done without putting heart in it is Karm-kand. To garland Me is a karma-kand, and not to garland is also a karma-kand. It means that anything done with love and heart in not a karma-kand. But when the same is done in a form of ritual or in mechanical manner it becomes karma-kand. While doing Arti if your mind is not there and always thinks something, then it remains nothing except karma-kand.
Many times, Meher Baba has said, “When My lovers do My prayer and Arti considering My idol or photograph I am not present there. But when they do it with sincere feeling in their heart, I am definitely present in that idol or photograph.
