The man whom these, cold and heat as described, do not trouble, do not shake, the man for whom pleasure and pain are equal, who is free of joy and dejection when pleasure or pain comes, the wise man, by his vision of the eternal Self: he, steadfast in the vision of the eternal Self's true nature and able to bear the pairs of opposites, is fit, is capable, for deathlessness, for the state of the deathless, that is, for liberation. And here is why it is right to endure cold, heat and the rest without sorrow and delusion.
