My son is 8 months old and I am at the end. The night time crying must end permanently. How do I make it so that he knows when the sun is in the sky, playtime is on and when it is dark you are not to be heard at all under any circumstance?

Wanting your child not to cry is akin to forcing you not to talk. Babies cry to communicate their needs. Establishing a good bedtime routine helps, but it's too harsh to want your child to "not be heard at all under any circumstance" at night. Not all babies sleep through the night. I suggest you read up on a few more parenting books to understand the development of babies.
