Gautama Buddha on Solitude

“Seclusion is happiness for the content one, one who sees the Dhamma that was heard; No ill-will is happiness in the world, restraint to living beings.”

“'This is an attachment; here there is little happiness, and little satisfaction; here there is very much misery; this is a hook.' Knowing this, a thoughtful man should wander solitary as a rhinoceros horn. Having torn one's fetters asunder, like a fish breaking a net in the water, not returning, like a fire not going back to what is already burned, one should wander solitary as a rhinoceros horn.”
