Dear list members,

I've been asked to find lesser known commentaries on the Yoga sutras of Patanjali.

I.e. commentaries made before 1900 and other than the commentaries of Vāchaspati Miśra, Bhoja Rāja, Vijñānabhikṣu, Rāmānanda Sarasvatī, and Swami Hariharananda Aranya.

If anyone could point these out to me would be great. 

Thanks,

Harry Spier
