Sammas is simply the name of Lord Azazel. There is nothing harmful about that meditation.
Older members and including myself have done the Sammas meditation and nothing has happened to me.
This meditation was eliminated, if I remember correctly, in October, November or December, so it was practiced by so many people.
The Sammas meditation also refers to the Chariot of Ra. Sammas in Akkadian means Sun. SAM is the mantra of creation. That's why Sammas is used to lift the snake. The ''S'' sound is used to raise the serpent Kundalini and represents fire, the spark of life.
The sound ''A'' is manifested by æther/Akasha and represents the one who balances fire ( S ) and water ( M ).
The sound ''M'' is the sound of manifestation and corresponds to water.
Sammas meditation prepares the kundalini to rise and harmonises the base chakra and the crown chakra. It is like a King and Queen meditation, only it works on other regions of the soul.
