English: The Yogasutra is an ancient Hindu text on Yoga philosophy. As a sutra, it is terse and needs interpretation and commentary called bhasya in the Hindu tradition. The Yogasutra is a widely followed and translated text since at least about the late 1st millennium CE.

The above photo is of a random, non-sequential sample page collection of a historic Yogabhasya manuscript. On the border in lower right corner is written "Ram", which sometimes marks the Hindu monastery tradition or Hindu temple the text was copied, studied or preserved in (in some cases, it represents the devotee's guru tradition). The manuscript may also highlight the colophon or some words with orange powder, corrections would normally be covered over with another color (in this manuscript, black) followed by notes on the margins. Personal commentary of a follower or another scholar are sometimes present in smaller script on the margins of a page.

The above 19th-century manuscript is archived and preserved at the University of Pennsylvania, which holds the largest number of South Asian manuscripts in North America. Some of its collection has been digitized and released in an ongoing effort as of 2018.
