MN 122 says:
Ananda, there is this abiding discovered by the Tathagata: to enter and abide in voidness internally by giving no attention to all signs. If, while the Tathagata is abiding thus, he is visited by bhikkhus or bhikkhunis, by men or women lay followers, by kings or kings' ministers, by other sectarians or their disciples, then with a mind leaning to seclusion, tending and inclining to seclusion, withdrawn, delighting in renunciation, and altogether done with things that are the basis for taints, he invariably talks to them in a way concerned with dismissing them.
Was the Buddha unsociable? If not, what is the meaning of the above verse?
