Rigpa

The nature of everything is open, empty and naked like the sky,
Luminous emptiness, without center or circumference: the pure, naked Rigpa dawns.

(Tibetan book of the dead)

This self-originated Clear Light, which from the very beginning was never born,
Is the child of Rigpa, which is itself without any parents--how amazing!
This self-originated wisdom has not been created by anyone--how amazing!
It has never experienced birth and has nothing in it that could cause it to die--how amazing!
Although it is evidently visible, yet there is no one there who sees it--how amazing!
Although it has wandered through Samsara, no harm has come to it--how amazing!
Although it has seen Buddhahood itself, no good has come to it--how amazing!
Although it exists in everyone everywhere, it has gone unrecognised--how amazing!
And yet you go on hoping to attain some other fruit than this elsewhere--how amazing!
Even though it is the thing that is most essentially yours, you seek for it elsewhere--how amazing!

(Padmasambhava)

Taken from the book "The Tibetan book of living and dying" by Sogyal Rinpoche. Ran into it yesterday. Seems pretty good. Rigpa, or Ground Luminousity or Clear Light is the place dead go, it says. It is not the known physical light.

I thought it is also like a description of the Higgs field which is supposed to underlie everything, including space-time and light. It is not yet directly observed and predicted to be a "scalar" field. Light is a vector field, as it has two polarised electrical and magnetic fields. A scalar field is like money. It has a value but not a commodity itself. Pure numbers are defined to be scalars. They are just numbers and do not represent any specific thing. Therefore numbers are idealisations. Like numbers are at the base of mathematics and science, Higgs field is at the base of everything we know. Similarly, according to Buddhism, life has Rigpa as the base, where spirits reside. When a spirit takes on life, it is bonded to it until death. Lately I saw a doco on ABC about near death experiences. Apparently there are serious scientists who say that Higgs field may allow impressions on it by life.

With the recent confirmations of dark energy and matter, space-time seems not as empty as it looks. In fact they constitute most of the observable mass, something like 95%.
