As it is said in the first line of the Hokkyo Zanmai, The Song of the Jewel Mirror Samadhi:” The teaching of thusness has been intimately communicated by buddhas and ancestors.” “Thusness”, “suchness”, “just this”, “as it is”, “tathata” "soku", "tathagatagarbha", …. you are looking right at it. It can’t be taught but you might need some help to see it.
