Has Anyone Here Opened up to Intelligent Infinity?

[Infinite]

From what I have read about other spiritual traditions, the closest thing I could find as a parallel to contact with Intelligent Infinity is what yogis call the state of samadhi. There are different level of samadhi and everyone experiences things differently, so for me it's hard to comprehend how far the experience of Oneness goes.

Yes. There are three main types of samadhi:

Savikalpa Samadhi, that's like "see" God, this is, you and God are two different things (that's which Ra called contact with intelligent infinity);

Nirvikalpa Samadhi , which is the fusion between you and God, there is no differentiation;

And the more advanced, called Sahaja Samadhi, a constant nirvikalpa samadhi, even in the daily activities.

I don't know which of the last two is which Ra called "penetration into intelligent infinity", but the truly master is who dominated the sahaja samadhi.
