Every act must be regarded as an offering to the Divine. It may not be easy to develop such an attitude. It does not call for abandonment of hearth and home or giving up your wealth and position. What I ask from you is to devote at least half an hour, in a day of twenty-four hours, to service. Is this beyond your capacity? If you can serve the government or someone else for eight hours a day, for the money you earn from them, experiencing in the process many trials and difficulties, can't you devote some time to win the grace of God, the benefit from which is immeasurable? What you earn through the grace of God will confer on you enduring benefits, greater than the wealth you earn by other means.
