We moderns have a bad habit of finding it difficult to see or envision this whole cosmos as the manifestation of one substance or essence this being Mind. This bad habit also includes our disbelief that it can be acquainted with in samadhi. But this is exactly what Buddhism is about. Some guy named Siddhartha long ago in India became directly acquainted with the stuff the cosmos is made of, including even his thoughts and yes, even his dreams. Is this a kind of myth or worse, just nonsense? No, not for someone who has done it; who never once considered it to be impossible.
The problem with most people who might believe this is nonsense is they are overly attached to the world around them consisting of their neighborhood, home, children, jobs, friends—yes, the list goes on. In other words, they are bewitched by everything from gnats to galaxies. Physical things dominate them completely as do their thoughts and emotions about those things. In such a confused state of mind how can they see what the Buddha saw when he awakened. For them it is not even possible. The negatives outweigh the positives.
To see this one substance requires some extraordinary skill of concentration. One has to become like a laser beam such that their concentration is so exact that it connects (samadhi) with the absolute substance. What comes as a result of this immediate connection is the realization that a super-pure substance is continuously manifesting itself as phenomena. It is like primary longitudinal waves always converting into secondary transverse waves—and you are really a longitudinal person. You realize that you were never really part of the visible, pluralistic transverse system that is always subject to birth and death.
From this awakened vantage point it is easy to see what real ignorance or avidya is. It is non-knowledge of the absolute substance. It is also easy to see why people are always suffering. They are always clinging to one side of existence: the always being born and dying side of existence. They don’t see or want to see the side of pure substance or the absolute medium that, despite the many forms it takes, is never changed; is always itself and free from suffering.
It is not that difficult to infer from this that there are countless advanced world systems where sentient beings are acquainted with the absolute substance; who see the pluralistic cosmos as a beautiful, grand illusion. They are also free from old age, death and suffering unlike we knuckle-dragging earthlings who are imbibing gallons of poison called delusion, hatred and greed.
