If you approach enlightenment from deity Yoga, the purpose is to play with your ego like you would play with lego blocks. You should be able to slowly replace your identity with that of a archetypical one, represented in some deity, not to become it, nor let it posses you, rather be aware of how the process works, which gives you insight in the nature of your being. With that goal in mind, any deity Yoga works. I recommend reading Sadhguru's free ebook about Shiva, called [Shiva - Ultimate outlaw](https://isha.sadhguru.org/mahashivratri/shiva/shiva-outlaw/)


Such a profound understanding of the human nature 👏🏼 Sadhguru is the best
