One should exercise one's power of discrimination in whatever one does. God always does things perfectly. Whenever I materialise a ring for a devotee, it exactly fits his finger. Even a goldsmith who takes measurement and makes the ring may commit a mistake.

He is goldsmith, but God is life-smith. He always does things in a perfect manner. Whatever service you undertake should be done perfectly. The one who serves and the one who is served, both should be satisfied. That is real service. The bliss that results out of such service cannot be found anywhere else.
