If a traveller does not meet with one who is his better, or his equal, let him firmly keep to his solitary journey; there is no companionship with a fool.
Just as a candle cannot burn without fire, men cannot live without a spiritual life.
If you find no one to support you on the spiritual path, walk alone. There is no companionship with the immature.
Of those beings who live in ignorance, shut up and confined, as it were, in an egg, I have first broken the eggshell of ignorance and alone in the universe obtained the most exalted, universal Buddhahood.
Surround yourself with people who make you happy. People who make you laugh, who help you when you're in need. People who genuinely care. They are the ones worth keeping in your life. Everyone else is just passing through.
Spend time with people who know how to use their days well. Just as iron sharpens iron, positive people will inspire you to be positive.
