Concerning Trekchö it is sufficient to just recognize the moment free from
thoughts of the three times, free of concepts. While in the state of Trekchö, you
apply the key points of the instructions of Tögal; do the three postures and the
three gazes, apply the key points, and leave the mind in rigpa. Then you see the
deities, they are visible, but they are intangible (nehmatateľné).
In Atiyoga, the deity is primordially present as our nature without any need to
be created. They are we. That is the short path.
When we experience the ultimate Tögal, the hundred peaceful and wrathful deities
will appear. One realizes that spontaneous presence is self-display.
