The Gaia Requiem for Strings, Soprano and Piano by Michael J. Stewart

Savikalpa Samadhi 

Savikalpa Samadhi is part of a series of orchestral and electronic pieces inspired by The Overview Effect. The Overview Effect has been described as a cognitive shift in awareness reported astronauts and cosmonauts during spaceflight while viewing the Earth from the perspective of space. The overview effect has been considered to be one of the stimuli that led to the Gaia Hypothesis.

Savikalpa Samadhi is scored for strings, piano, soprano and boys' choir.

After I came back and tried to understand what this experience was all about I could find nothing in the science literature about it and nothing the religious literature that I looked at, so I turned to a local university and asked to help about what I saw and when the came back to me a few weeks later they said that they well in the ancient literature we found a description called Savikalpa Samadhi which means you see things as you see them with your eyes but you experience them emotionally and viscerally as it was ecstasy and sense of unity and total oneness.

One of the astronauts said when we original went to the Moon our total focus was on the Moon, we weren’t thinking about looking back at the Earth, but now that we have done it that may well have been the most important reason we went.

It really is striking and it is really sobering to see this paper-thin layer and to realise that that little paper-thin layer is all that protects every living thing on Earth from death from the harshness of space.

We should be the heart and mind of the Earth, not its malady. So let us be brave and cease thinking of human needs and rights alone, and see that we have harmed the living Earth and need to make our peace with Gaia. We must do it while we are still strong enough to negotiate, and not a broken rabble led by brutal war lords. Most of all, we should remember that we are a part of it, and it is indeed our home.

I can only describe what I have seen - looking down at the Earth and you see that line that separates day into night slowing moving across the planet. Thunderstorms on the horizon casting these long shadows on the horizon as the Sun sets and then watching the Earth come alive.
