Is astral projection—which is the soul's departure from the etheric body and its wandering in places—permissible or forbidden in Islamic law?

Astral projection is an unfounded conjecture based on the hypothesis of the etheric body, which modern science has proven does not exist. These ideas are promoted by Eastern philosophies and the therapeutic applications derived from them, advocating the development of human powers to reach supernatural abilities without the need for religion or divinity. Relying on such sorcery is forbidden (haram), and whoever relies on it has disbelieved in God and revelation.
