An educated man reads about the soul and finds nothing there — while beside him someone quite simple hears the same words and weeps. We explain it by capacity: one has the gift, the other does not. Yamaraj answers Nachiketa differently. Those who walk the path of preya — after what gives joy today, tomorrow, the day after — are mūḍha, dull; they will not understand ātma-tattva even if they take it up in earnest. And it is not about intelligence: the mind has simply been turned toward the nearer gain for so long that it makes out nothing else. A heart set on śreya, on the ultimate good, is ready to give up everything worldly for it — because it sees how little that costs.
