"You must reform your mental traits and habits. Cultivate the habit of never causing pain to others. Try to understand others, sympathise with and help them. Train yourself to take insult and criticism as decorations awarded to you. Be friendly with everyone, whatever be their nature or conduct. A joyous disposition is necessary for spiritual progress, but many things and situations deprive you of the atmosphere of joy. So you must pray sincerely in order to be free from such obstacles. The recital or repetition of prayers (mantras) will be of great help."
