c29.38

§ 192. The tradition of an ancient and obsolete custom of sister-marriage amongst the Śākyas had misled some scholars into theories of race-origins. Such ancient and once living custom or law is accepted by the Vedic literature to have existed in the orthodox race. Buddhist tradition also does not limit it to the Śākyas. It extends it to the Ikshvāku royal dynasty and the Ikshvākus were not new comers; they were never desacramented. They are as ancient as the Vedas. If the Ikshvākus were Aryan, their offshoot the Sākyas cannot be otherwise.
