Yes, this is an precious translation by Heidi. She told me she wanted to make a yogi version of that book but I guess she is to busy. Highly recommended.
The Mahayoga view is that everything is inseparable purity and equality. Tsele Natsok Rangdrol put it like this:
"The practitioners of mahayoga consider sights and sounds, the mandala of the peaceful and wrathful ones and so forth to be superficial truth. Being beyond arising, dwelling, and ceasing is the ultimate truth. The nonduality [of these two aspects] is the 'indivisible two truths.'
And in Dzogchen, the Pearl Garland Tantra;
"All these variegated appearances,
Like perceiving a rope to be a snake,
By perceiving them to be what they are not
Both the outer world and inner inhabitants were formed.
When examined, it is simply a rope;
The world and beings are primordially empty.
Ultimately, they are superficial forms.
The natures of the two truths
Are samadhi and mere worldly convention.
Ultimately, there is no connection,
A s everything is liberated in its essence --
The space of emptiness."
"To reject practice by saying, 'it is conceptual!' is the path of fools. A tendency of the inexperienced and something to be avoided."
