vedāvirodhi cettantraṃ tatpramāṇaṃ na saṃśayaḥ |
pratyakṣaśrutiruddhaṃ yattatpramāṇaṃ bhavenna ca ||

Tantra is accepted as the authoritative proof then and then only when it contradicts not the Vedas. Whatever goes clearly against the Vedas can in no way be accepted as a proof. In matters concerning Dharma, the Vedas is the Sole Proof. Therefore that which is not against the Vedas can be taken as proof; otherwise not. Whoever acts Dharma according to other proofs than what is ordained in the Vedas, goes to the hell in the abode of Yama to get his lesson. So the Dharma that is by all means to be accepted as such, is what is stated in the Vedas. The Smritis, the Purânas, or the Tantra S’âstras can be taken also as authoritative when they are not conflicting to Vedas. Any other S’âstras can be taken as authoritative when it is fundamentally coincident with the Vedas. Else it can never be accepted.
Those who do injury to others even by the blade of a Kus'a grass used as a weapon, go to hell with their heads downwards and their feet upwards. Those that follow their own sweet free will, that take up any sort of dress (e. g. Bauddhas), those that follow the philosophical doctrines called Pâs'upatas, and the other hermits and saints and persons that take up other vows contrary to the religions of the Vedas, for example, the Vaikhânasa followers, those who brand their bodies by the hot Mudrâs, at the places of pilgrimages, e. g. Dvârkâ, etc., they go to hell with their bodies scorched by red hot brands (Tapta Mudrâs). So persons should act according to the excellent religions commanded by the Vedas. Everyday he should get up from his bed early in the morning and think thus:-- “What good acts have I done, what have I given as charities? Or what I advised others to do charities what greater sins (Mahâpâtakas) and what smaller sins have I committed?” At the last quarter of the night he should think of Para Brahmâ. He should place his right leg on his left thigh and his left on his right thigh crosswise keeping his head straight up and touching the breast with his chin, and closing his eyes, he should sit steadily so that the upper teeth should not touch the lower jaw.
He should join his tongue with his palate and he should sit quiet, restraining his senses. He should be S’uddha Sattva. His seat should not be very low. First of all he should practice Prânâyâma twice or thrice; and within his heart he should meditate the Self of the shape of the Holy Flame or the Holy Light. (Om Mani Padma Hum.)
