Yogacara, one of the two main schools of Mahayana Buddhism, is often referred to as the “Mind Only” school. This is not to say that anything outside the mind is unreal. It is intended to help you see that what you are experiencing is coming to you in some form of perception in consciousness, based on the six senses and the assumption of a separate self. When there is transformation at the basis of consciousness, that everything is dependently arisen is fundamentally seen. There is no separate self to be found anywhere.
