We must discover at which times we have manifested our devil or our animal spirit. We want a human spirit, and self-realization is the search for this human spirit; everything must become human in us. But how should we accomplish this? Read the Bible and other holy scriptures? All these books tell us what we should do, but we must also find the store of goodness that is within us, in our heart. As we cultivate our heart it rises. By asceticism one can develop one's soul and reach ecstasy, but what is the use of Samadhi if we are not first human? If we want to live in this world we must be human. The ascetic should live in the forest.
