4th dimension is said to be accessed in the practice of Kundalini and secret serpent power that is said to be coiled at the base of the spine is elevated up the body to the cranial chakra, where the pineal gland is then opened. The opening of Peh (the mouth) is also the opening of Ayin, the Eye of Set, or Shiva, whose sight is in Ain (or “ajna”). The opening of the Eye of Shiva is symbolized by the unfolding of the tetrahedron, a 3-dimensional hexagram. This unfolded, blossomed eye is called the “Sri Yantra” and is said to be the gateway to Daath (“knowledge”, equated with the Abyss/bottomless pit, said to be the domain of Shiva/Apollyon the Destroyer in the Book of Revelation). As the opened mouth, or eye, the Sri Yantra is the turning point between the 3rd and 4th dimensions of the universe.
“And they had tails like unto scorpions (demons released from the opened Abyss), and there were stings in their tails: and their power was to hurt men five months. And they had a king over them, which is the angel of the angel of the bottomless pit, whose name in the Hebrew tongue is Abaddon, but in the Greek tongue hath his name Apollyon (the Destroyer).” (Revelation 9:10,11)
