Question: You have said that earth is the place where souls can make progress. So how is their prayer aiding these beings on other planets?Sri Chinmoy: Their prayer is aiding them, but for God-realisation the earth planet is needed. Other planets will not give realisation. The progress that is necessary for God-realisation, the earth planet alone can give. On other planets beings can make progress, but not for God-realisation. They will get light, more light, abundant light. But they have to come down here to realise God. On each plane they can receive light. But for nature's transformation or God-realisation, they have to come here. God has chosen this planet alone for God-realisation. In other places you can accumulate and accumulate, but you have to spend the wealth here.
