do mantras help to have astral projection

do mantras such as faraon, egipto, taire and laras help to astral project? i’ve also seen techniques about envisioning your heart and going deep inside it getting into a cell as you go asleep to help

What helps is concentration on a single point. Mantras are meant for that. You hold your attention to something so you dont get asleep. Then you will find that you can cross to the dream or astral plane without loosing your consciousness.

Mantras are also sacred vibrations, their sound and right pronunciation awake spirtual centers in your energetic body.
