I've been reading several books (planning to order way more) about gnosticism and I still feel as if I haven't achieved gnosis. Any help /x/?

Recently I became aware of the Tibetan Bhuddist concept of the Vajra Body, or Diamond Body. Its apparently the concept of the physical body or consciousness undergoing some kind of transmutation and becoming near immortal, supposedly hard as diamonds, The color red is mentioned in some instances. In the gnostic texts referencing this is supposedly seen as a way for the awakened spirit to continue to exist in the material universe of time/death while also having higher abilities and not being purely bound by the conditionality of the Demiurges loosh farm, spiritual evolution hierarchy of beings, traveling back and forth between the non-demiurgic realms and this one, at will.
