Yoga is a Hindu concept and an integral part of Hindu philosophy. Samaneguy is right here that Buddha had actually rejected Yoga, but someone is trying to portray it as a Buddhist concept here in this article. Description of Yoga in some Buddhist texts doesn't make it a Buddhist philosophy. 

This edit of  can be clearly seen as an attempt to put Buddhism in the very lead using the same reference which is present in the later part of the lead section which says that various traditions of Yoga are found in Hinduism, Buddhism and Jainism. He took only Buddhism from this and uplifted it to the very lead. In his next edit, he replaced Template:Hindu philosophy by Template:Buddhist philosophy giving a misleading edit summary. Here, he replaced image of Shiva by that of Buddha giving confusing edit summary again. These edits can't be taken as good faith edits at all. -
