The Great Garuda states:
In groundlessness, uncontrived and free of anything to rely upon, assuming specific postures and trying to relax in lucidity bind one to apparent phenomena. If one’s mind is not free of extremes and not unbiased, mental analysis and speculation prevent one from experiencing the way of abiding. Without the confidence that comes from resting naturally in timeless freedom, in which nothing need be done, realization is constrained by wishful thinking and fleeting meditative experiences. Without the key point of resting naturally and not seeking anything, awareness is obscured by reliance on teachings that concern causality.
Having come to a thorough understanding of the way of abiding as ineffability, one reaches the definitive conclusion that its nature is openness. The transmission of atiyoga, the very pinnacle of all spiritual approaches, is like space, without limit or center. The greatest of the great is the spacious mind of Samantabhadra, its nature a supreme and uninterrupted evenness
Deep Immersion in Awareness states:
When arising, things arise equally, without being better or worse. When abiding, they abide equally, without being better or worse. When freed they are freed equally, without being better or worse. Although they arise unequally, they arise from the basic space of their equal-ness. Although they abide unequally, they abide in the basic space of their equal-ness. Although they are freed unequally, they are freed within the basic space of their equal-ness
