The Purpose of Meditation in Patanjali Yoga

In Vedanta, meditation is not for Moksha or Jana also. Meditation can give you a vision of your Ishta Devatha but that is not the purpose of meditation in Advaita Vedanta. Yoga clearly mentions whole chapter on all sorts of extraordinary superpowers you can get. You can easily be part of Marbel comics, DC comics and like be a superhero. But that is uniformly condemned in all religions.
