MAITREYA.--You have told me, venerable sir, that an ancestral rite is not to be looked upon by certain persons, amongst whom you mentioned such as were apostates. I am desirous to learn whom you intended by that appellation; what practices bestow such a title upon a man; and what is the character of the individual to whom you alluded.
