Most people worship God as their order supplier. But Vrindavan consciousness is simply to give pleasure to Krishna and to not expect anything in return except the opportunity to serve. And when we chant the holy names with this spirit, Krishna reveals himself in full.
Simply we have to desire to please Him (Krishna) and not desire anything for ourselves. Then we become simply instrument for his will. This is the important essence of Krishna consciousness. — In his Letter to Atreya Rishi, 20th Oct, 1973.
Even a small service performed with love & devotion pleases Lord Krishna.
Even if devotees excuse those who insult them, Krishna takes a diffrent position and he is strict on this matter. Krishna will not excuse or tolerate any insult of his devotees. If we want to please Krishna, we must never insult his devotees. — Lecture on Bhagavad Gita, 01.26-27, London, 1973.
Total absorption in playing flute for pleasure of Lord Krishna.
Krishna tells in Bhagavad Gita, "Ananyas Cintayanto Mam Ye Janah Paryupasate" that if we just approach him with sincerity, then He will carry what we lack and preserve what we have". Just put your sincere and honest efforts to please Krishna then all your hearts, desires for the welfare of others can be fulfilled.
