Mahāsuññatasutta

Suttapiṭaka · Majjhimanikāya · Vol. 14 · Section 345

[345] "Ānanda, a bhikkhu does not shine who delights in company, who takes delight in company, who is devoted to delighting in company, who delights in a group, takes delight in a group, and rejoices in a group. Indeed, Ānanda, that a bhikkhu who delights in company, who takes delight in company, who is devoted to delighting in company, who delights in a group, takes delight in a group, and rejoices in a group, will become one who obtains at will, without trouble and without difficulty, the happiness of renunciation (nekkhamma), the happiness of seclusion, the happiness of peace, the happiness of awakening — this is not possible. But when a bhikkhu dwells alone, withdrawn from the group, it may be expected of that bhikkhu that he will become one who obtains at will, without trouble and without difficulty, the happiness of renunciation, the happiness of seclusion, the happiness of peace, the happiness of awakening — this is possible. Indeed, Ānanda, that a bhikkhu who delights in company, who takes delight in company, who is devoted to delighting in company, who delights in a group, takes delight in a group, and rejoices in a group, will enter upon and dwell in the liberation of mind (cetovimutti) that is temporary and agreeable, or in that which is non-temporary and unshakable — this is not possible. But when a bhikkhu dwells alone, withdrawn from the group, it may be expected of that bhikkhu that he will enter upon and dwell in the liberation of mind that is temporary and agreeable, or in that which is non-temporary and unshakable — this is possible. Ānanda, I do not see even a single form (rūpa) from the change and alteration of which there would not arise sorrow, lamentation, pain, grief, and despair in one who is impassioned by it, who has taken full delight in it."
