does anybody know when the "veil" is lifted?

[Infinite]

In incarnation, the veil will be lifted if the kundalini of the seeker arise to violet-ray chakra. In the hinduism this is called nirvikalpa samadhi, a total union with the Creator (penetration into intelligent infinity). Here, a little stretch from Yogananda:

To tear the veil of maya is to pierce the secret of creation. The yogi who thus denudes the universe is the only true monotheist. All others are worshiping heathen images. So long as man remains subject to the dualistic delusions of nature, the Janus-faced Maya is his goddess; he cannot know the one true God.

The world illusion, maya, is individually called avidya, literally, “not-knowledge,” ignorance, delusion. Maya or avidya can never be destroyed through intellectual conviction or analysis, but solely through attaining the interior state of nirbikalpa samadhi.

That is correlated with Ra informations:

84.21 Questioner: Is there any way to tell which ray the transfer was for an individual after the experience? Is there any way for the individual to tell in which particular ray the transfer occurred?

Ra: I am Ra. There is only a subjective yardstick or measure of such. If the energies have flowed so that love is made whole, green-ray transfer has taken place. If, by the same entities’ exchange, greater ease in communication and greater sight has been experienced, the energy has been refined to the blue-ray energy center. If the polarized entities, by this same energy transfer experience, find that the faculties of will and faith have been stimulated, not for a brief while but for a great duration of what you call time, you may perceive the indigo-ray transfer. We may not speak of the violet-ray transfer except to note that it is an opening to the gateway of intelligent infinity. Indeed, the indigo-ray transfer is also this but, shall we say, the veil has not yet been lifted.
