The source of loving service for others is a heart that is aware, sensitive and conscious of one's own feelings and the feelings of others -- this is the goal of meditation.
Seeing beauty in a flower could awaken humans, however briefly, to the beauty that is an essential part of their innermost being, their true nature. The first recognition of beauty was one of the most significant events in the evolution of human consciousness. The feelings of joy and love are intrinsically connected to that recognition. Without our fully realizing it, flowers would become for us an expression in form of that which is most high, most sacred, and ultimately formless within ourselves.
