the throb

When the universe began it began as a vibration, a throb,
"a kind of movement" Tantric philosophy says.
The technical term for this vibration is Spanda.
This throb, this "kind of movement" propagates through the universe.
It could be said that this vibration, this wave exists in different forms at
different levels of existence.
But the more correct way of viewing, Spanda, the vibratory wave is that this
wave exists as the different levels of existence.
