It is a state of ecstasy. It also is the state at the core of our existence, but some know and some do not. Everything around us is born of mind. Come to understand this. To go into that unmanifest state, you have to be like a little child.
Little children have no mind.
The children are nonpossessive, nonattached. They take in everything in sight, drawing it into themselves. Yet, when you ask them what they ate, their answer is often silence. Mum is the word. This is because they are mindless, they have no mind.
