Explanations

EMPTY YOUR MIND= Stop thinking.

FORMLESS= Without form. The suffix –LESS means “without” and is used to make adjectives: noun + -less = adjective:
- heartless = without a heart (without feelings): he’s a heartless man.
- hopeless = without hope (desperate): I’m hopeless, there’s nothing I can do well.
- lifeless = without life (dead): The poor cat rested lifeless on the pavement.

SHAPELESS= Without shape, formless.

NOW, = He uses NOW twice, and in both cases it doesn’t mean anything, it’s simply a way of starting a sentence, very commonly used when giving explanations or instructions, etc.:
- Now, everybody listen to me.
- Ok, now, we need to buy some more milk.
- Now, you go to the police and you wait here. I’ll try to catch the robber.

FLOW= Move like a river, smoothly and going round obstacles instead of crashing into them.

CRASH= Collide, bump. To break violently or noisily; smash.
