From the Holy Text of Tibetan Buddhism: Sixty Songs of Milarepa – Songs 54-56 & 58-60, Part 1 of 2

“Revered One, since your mind no longer changes, there is no need for you to practice meditation. Therefore, for the sake of sentient beings please come to our village and preach the Dharma for us.” Milarepa replied,” Practicing meditation in solitude is, in itself, a service to the people. Although my mind no longer changes, it is still a good tradition for a great yogi to remain in solitude.”
