The practice of the secret method corresponds to this deity, and finally it proves to be the same as this deity. And this deity is Buddha, or Bodhisattva, King Kong, King Ming, etc.
For example, Harraca Lanasa's oath:
Those who see my body develop bodhicitta, those who smell my name break evil and cultivate good, those who smell my dharma gain great wisdom, and those who know my heart become Buddhas.
Knowing my heart is to correspond to his heart and prove his heart. Repair your heart to be like him, just like quantum entanglement theory, so that you can contact each other and feel each other. Scientifically speaking, this means that we are connected to their network. It can also be said that this is the infinite wisdom and magical power of the deity network. From the realm, the realm of this deity is our realm.
