The Yoga Sutras by Patanjali is an incredible resource for anyone interested in Yoga. This app is a swiss army knife study guide complete with a searchable sanskrit dictionary, and audio chanting of every verse.
Unlike the book form, you can now easily scan through its contents by topic, etymology, translation, and commentary. You can listen to each verse, and memorize them with ease.
This project took a year and a half researching and translating this ancient text and compiling it into an pocket sized tool. Reading from Edwin Bryant, B. K. S. Iyenger, Swami Satchidinanda, the author's aspiration was to write a sober commentary. A commentary that offers a logical approach to some of the more phenomenal things discussed such as levitation, immortality, and enlightenment.
