Is Tantra part of the Sruti or Smriti? I am a bit confused about where to place Tantra. Please answer with references.
Tantra is placed under Sruti by Kulluka Bhatta. He is one of the famous commentators on Manu Smriti. In his commentary on Manu Smriti (Chapter II, Verse 1: Learn the Law always adhered to by people who are erudite, virtuous, and free from love and hate, the Law assented to by the heart.), he quoted Harita, who said that there are two types of Srutis - Veda and Tantra. Here is what he said -
श्रुतिश्च द्विबिधा वैदिकी तान्त्रिकीच (śrutiśca dbibidhā vaidikī tantrikīca)
However, Manu himself declared that Sruti (Scripture) should be recognized as the Veda. (Chapter II, Verse 10).
श्रुतिस्तु वेदोबिज्ञेयो (śrutistu vedabigya)
So Manu himself did not recognize Tantra as Sruti and he is the authority.
The Illustrated Encyclopedia of Hinduism (Vol. 2) by James Lochtefeld also included Tantra under the Smriti category.
So Tantra is part of Smriti.
