Antinomianism is defined as holding that, under the gospel dispensation of grace, moral law is of no use or obligation because faith alone is necessary to salvation....

Tantras

Tantras refers to numerous and varied scriptures pertaining to any of several esoteric traditions rooted in Hindu and Buddhist philosophy. Although Buddhist and Hindu Tantra have many similarities from the outside, they do have some clear distinctions. The rest of this article deals with Hindu...

"Lastly, the doctrine that the illuminate knower of Brahman (Brahmajnani) is above both good (Dharma) and evil (Adharma) should be noted. Such an one is a Svechacari whose way is Svechacara or "do as you will". Similar doctrine and practices in Europe are there called Antinomianism. The doctrine is not peculiar to the Tantras. It is to be found in the Upanishads, and is in fact a very commonly held doctrine in India."

Woodroffe (1951: pp.440-441) also goes on to state that:

"In Svecchacara there is theoretical freedom, but it is not consciously availed of to do what is known to be wrong without fall and pollution."

Svecchācāra is important in the Nath

Nath

The Sanskrit word nāthá or नाथ, is the proper name of a Hindu initiatory tradition and the word itself literally means "lord, protector, refuge"...

 Sampradaya evocation of their realized ideal, of the Avadhuta; as Mahendranath states:

"Sveccha means one's own wish or free will. Svecchachara means a way of life where one acts as one wishes and does what is right in one's own eyes. Doing one's own Will. The concluding Sanskrit expression in the Avadhoota Upanishad is "Svecchachara Paro."

The term "Paro" means a mysterious or secret pattern to that action done by one's own Will. In other words, we do our Will but with discretion, not making it too obvious, nor to harm or hurt other people. Yet this is also a typical Nathism; a complete reversal of Vedic morals and philosophy."

This term is employed in the closure of the Avadhuta Upanishad.

Mahanirvana Tantra

The term 'svecchācāra' also appears nine times in the Mahanirvana Tantra first translated into the English from Sanskrit by Woodroffe (1913).

Kali Tantra

Svechchhachara, “following one's own [true] will” is also evident in the Kali Tantra 8.19.
