There are several different styles of Yoga but three are most as from my perspective, each designed for different purposes.

Bhakti Yoga, or devotional Yoga, is the most natural path for those who are dominantly seeking emotional fulfillment and well being, which I completely agree as these type of Yoga are performed by sadus (rituals). Religious beliefs are strongly taken to be successful in this practice. Visualizing, thinking, and feeling that the Lord is sitting or standing before him. This Yoga is very powerful as I practice this myself. I have seen a change from the day I started and I am now. Critical thinking, disappearing the thoughts of material pleasure and more joining path to the Lords are the advantages that I felt practicing this Yoga.
