The mind of our teacher is luminous buddha nature. Our mind dissolves into the teacher’s mind, which also means that all our thoughts dissolve in luminous buddha nature of dharmadhatu. In the end only luminous buddha nature exists, which is in fact the realisation state of buddhas and bodhisattvas. The state of realising the Dzogchen for the first time is similar to this.
