I would also NOT recommend it--especially at age 17. I don't necessarily believe that entities such as djinn exist "out there" in some etheric space but I do believe that lots of creatures live as elementals and archetypes within one's own consciousness--and you don't want want them flying out. Long effort in magical and mystical and psychodynamic disciplines (of whiich so-called Kundalini yoga and chakra meditation is one) is required to 1) bring out these entities and 2) effectively work them or work with them rather than having them work you.
Rather than thinking about asking an entity to posses you (plenty already are, actually), try experimenting with servitors and personal god-forms instead. (IMG:
