Sarvadarshanasangraha 15.28

15.28

according to this traditional text of Yājñavalkya; so how can Patañjali be the teacher of yoga? If this is urged, quite true: for this very reason, thinking that, because yoga was scattered here and there in the Purāṇas and elsewhere, its meaning was difficult to grasp, the venerable Lord of Serpents, an ocean of compassion, wishing to gather together the essence, commenced an *anuśāsana* (subsequent instruction), but not a direct original instruction (*śāsana*). When this word *atha* has the sense of commencement, then the sentence-meaning is established as follows: “The treatise that is a subsequent instruction on yoga is to be known as commenced.”
