So if the Taliban community or the US military complex community(don't mean to single out the Taliban or the US) at this moment were to receive a transmission of Vajrasattva providing all the cognitions were correct. Why would the process of purification commence?
Huh? What are you talking about? How do you suppose people that have no interest would "receive transmission" and have the "process of purification commence". It is not as if Vajrasattva unilaterally imposes Dharma on people.
Why is so much co-emergence required from the other side considering the apparent attributes of Vajrasattva?
The "great vehicle" Buddhahood seems in complete.
Cessation of suffering from a "Great Vehicle" view has only occurred on paper.
I think this entire line of thought can be traced back to how the word "for" is being used. A mother makes dinner "for" her family, so they don't have to do it themselves. It's not like that.
A man goes to medical school "for" others. He then can prescribe medicines. It is still up to the patient to properly follow his advice and take the pills. (The analogy of Buddha as doctor is a standard teaching, although I've adapted it a bit.) It's more like that, IMHO.
In the Tantra of the Beautiful Auspiciousness (bKra shis mdzes ldan gyi rgyud), this "Great Primordial Purity" (spyi gzhi) is defined as follows:
What is known as "The Great Primordial Purity”
Is the state abiding before authentic Buddhas arose
And before impure sentient beings appeared;
It is called the great Primordial radiance of immutable awareness.
