The Lokayatikas say:—Religious ordinances should not be observed, for they bear a future fruit, and at the same time it is also doubtful whether they will bear any fruit at all. What foolish person will give away that which is in his own hands into the hands of another? Moreover, it is better to have a pigeon today than a peacock tomorrow; and a copper coin which we have the certainty of obtaining, is better than a gold coin, the possession of which is doubtful.
