I actually have that book in Kindle format (I don't know if that makes any difference). I didn't see any thing on house purification. I did see the section on offering the tamagushi and misogi. I also had another question about ancestor worship and setting up a space for that. I didn't know if you could help me with that or not.
I would like to setup a home shrine for my departed wife.
Is it acceptable to cleanse the site, use a one door god shelf and place a picture of my wife in it?
I have a quiet area above the fireplace where once placed, the the god shelf would face East.
Is it necessary to have a spirit tablet in the shelf or can I simply use it with the picture of my wife as an ancestor shelf?
