I am so glad to understand that as soon as your finances are almost depleted, Krishna sees to everything. This is the process of Krishna Consciousness. If we are sincere, Krishna will supply us with all necessities of life. When we serve some mundane master, he gives us sufficient salary, so when we serve the Supreme Master, how it is possible that He will keep us fasting? Actually due to our lack of Krishna Consciousness sometimes we become disturbed with shortage of funds. But we should be confident that our necessities will certainly be fulfilled by the Supreme Lord. The same incident sometimes happens in New York temple. When there is a shortage of funds, sometimes they find money accidentally without knowing the source.
