Knocking

Would you walk into a stranger's house without knocking?

It seems like people are not being taught about knocking. Conjure is one of the most straight-forward magics in the world, but it seems like people either over-think it and complicate it, or they underestimate it and strip away important facets of the practice.

When we approach a grave for spirit work, we knock at the headstone first. When we work with a root, we knock on it to wake up and call upon the spirit of it. We knock on candles to awaken the power we've called into them. We knock at the air or on an altar piece when addressing spirits. Knock knock knock.

You don't barge into strangers houses unannounced and demand the people do stuff for you, so why would this be acceptable on a spiritual level?

Matthew 7:7-8 - Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened.
