A twice-born brahmana (dvija) gains his life by the grace of his parents through the process of purification known as garbhadhana. There are also other processes of purification, until the end of life, when the funeral ceremony (antyesti-kriya) is performed. Thus in due course a qualified brahmana becomes uninterested in materialistic activities and sacrifices, but he offers the sensual sacrifices, in full knowledge, into the working senses, which are illuminated by the fire of knowledge.
