Look into your heart. Find out what special talent God has given you. Develop it, and use it for the good of others. Eradicate negative qualities by the practice of their opposite virtuous traits. Virtue begets virtue. If one virtue is developed, another virtue will automatically come to you.
Learn to live in such a way that you send out only helpful thoughts. If everyone practised the yamas and niyamas, there would be no need for atom bombs, arsenals, forts, armies, navies and air forces. Then there would be peace everywhere.
Man makes himself miserable by separating himself from others. You are lonely because you build walls instead of bridges. See life as a whole. The world is one home and we are all members of one human family. Separation is death. Unity is eternal life.
