You can’t. It practices you.
Mysticism is not a religion, a cult, or a dogma. It is an overpowering infusion of an individual experience of an indescribable reality of existence beyond general human experience or understanding.
This Mystical Experience of Reality (MER) reveals a view of all things known and unknown in which all things have always had and always will have their existence in one description or another, where all things are and we are that, and the experiencers of this MER feel an accepted part, now and forever.
All this is imparted in a feeling of personal acceptance so powerful it extinguishes mere human love which is just lust, anger, greed, attachment and ego.
This non-human, mystical, experience of cosmic love is profoundly humbling, generating a rebirth, an individual reincarnation that fills the recipient with profound gratitude, a cleansing of all human concerns in a dissolving joy of final true belonging in everything.
The recipient now exists knowingly in an everything that is everlasting, where everything is known, where all is well.
There is no question of the recipient of this knowledge practicing it. He or she IS it, forever.
Why the recipient becomes part of the developing human manifestation of this Reality again after this experience is not clear. After the MER, being human again seems a constant, unpleasant, inconsequential challenge only mitigated by the certain knowledge that though being human is an incurable condition, it is terminal.
So a mystic’s practice becomes just being, now knowing what they are – something more than just human.
Reality awaits, practice or no practice.
