Depending on the different course modules, we have other numbers of yoga postures, but according to the Hatha Yoga Pradipika, which is an anthology that combines many Hatha texts. It includes fifteen primary postures - 7 of which are seated, and eight are non-seated. The additional 69 poses are also there, which combines to give a total of 84 asanas. But as we said, you aren't going to perform all these yoga postures in one course.
