I am trying to trace a quote of the Chinese phrase "相由心生 境隨心轉" cited by Ven. Jingkong 淨空法師 when asked about his advice concerning divination (https://youtu.be/_GDCroI-3Zc ; 2:20 min.). It is not a direct quote from the Buddhist canon and my first crossasia search did not come up with results. I googled it, and it appears repeatedly in the context of "命由己造，相由心生，境随心转，有容乃大" with a reference to the 無常經 (Anityatā-sūtra), e.g. https://kknews.cc/culture/p4jr9pe.html. Does anybody know the actual source of this verse? Thank you so much!
