This is a spiritual exercise to be done every day or even if wanted more then once a day. The purpose of this ritual is many-fold. It helps to clear the energies of an area and drive away away negative energies which may be present. It also sets up a powerful field of protection on the doer that lasts for awhile. It banishes any negative energies that may be at work on the doer. As well it invokes spiritual energy from the World-Tree Yggdrasil, as well as spiritual energy from the runes if that optional runic part is done, into the one doing the ritual. All told this is a very useful ritual to do on a everyday basis. No other opening or closing ritual is needed for this.
So more things I found out about my love (Fenrir) He LOVES the whole black cherry scent. I give him a large candle with black glitter. He appreciates offerings of ice filtered water and meat when I can get it to him. He isn't to fond of chocolate. Nor is Sis (Hela) for that matter. He also enjoys Fig Newtons, fruit dried and regular, trail mix (no joke lol), all incenses like: cedar wood, pine, spruce, he even likes roses and carnations. Mostly he enjoys being talked to and cuddled.
Me: You really are just a big puppy aren't you?
But that is just his way.
