Some medieval era Indian texts on Yoga list Rajayoga as one of many types of yoga.For example, the Sarvanga yoga pradipikå, a Braj-bhashya commentary by Sundardas, from the 17th-century, teach three tetrads of Yogas. The first group is Bhakti yoga, Mantra yoga, Laya yoga, and Carcha yoga; the second group is Hatha yoga, Raja yoga, Laksha yoga, and Astanga yoga; the third is Samkhya yoga, Jñana yoga, Brahma yoga, and Advaita yoga. Of these twelve, Sundardas states that Rajayoga is the best yoga.
