By the word "human" is indicated the fourfold aggregate of living beings—womb-born, egg-born, and the rest. Its condition is human existence. In that [existence], which has the nature of cyclical transmigratory life, which is devoid of inner substance like a plantain stalk, and which is perishable in an instant like a water bubble, whoever seeks—searches for—a substance, something permanent, is thoroughly deluded, his mind utterly disordered. Therefore, this should not be done by you who understand the true nature of cyclic existence. // 3.8
