So i will simply explain to the King what is the meaning of Paying Homage as the King expected homage from Padmasambhava earlier and Vimalamitra later upon the consecration of the Temple.
"A prostration (Pali: panipāta, Skt.: namas-kara, Ch.: li-pai, Jp.: raihai) is a gesture used in Buddhist practice to show reverence to the Triple Gem(comprising the Buddha, his teachings, and the spiritual community) and other objects of veneration."
I have stated that Buddha Dharma are ways or methods and as per Avatamsaka or Flower Adornment Sutra, these ways are Infinite or Immeasurable! :)
Can you think of ways to help or advise King Trisong Detsen, so that his clothes won't catch Fire?
The Answers can be found in Avatamsaka Sutra or Zen Patriarch Bodhidharma's teachings as well as many other dharani!
Quoting the passages from Lotus Born, does not naturally means you understand the True mechanics behind.
Thus you also failed to answer the question to the point!
Rephrasing your comments also won't help, unless you know what Vimalamitra is talking about when he does his prostration to Vairochana's statue!
This question appears easy but quoting Vimalamitra actually complicated matters for all of you!!!
