I find it tough to apply knowledge in such situations, when there is no food and no power.
You do not have to apply knowledge, just be spontaneous.
Knowledge is already inbuilt in you. You have to accept situations, live in the present moment and serve people. This is the knowledge. Do not try to apply any more knowledge; it is not needed. Be spontaneous and have the faith that something good will come out. Have the faith that your prayers will be answered.
