“By daily doing such acts of kindness and sympathy, man develops mercy. Hatred vanishes. His hard egoistic heart is gradually softened. He cultivates cosmic love. His heart expands. He has a wider outlook on life. He tries to feel his oneness with all beings. His old feeling of separateness on account of selfishness and egoism is gradually thinned and eventually eradicated. He learns that he can be happy only by making others happy, by serving others, by helping others, by removing the sufferings of others and by sharing what he has with others.” Swami Sivananda
