I think that's a very sweet idea of consecrating a home. I think you can decide on your own way of doing so. whatever means something to you. Chucks suggestion of sex on the carpet is one way. Having a new home is in a way, like a marriage. You are taking a new home to have and to hold. So, sex, is one way, solo I think would be best.
I've lived in my home 17 years, and it seems like a part of me. I don't think I've ever gone through some sort of commitment ceremony. Maybe I should. I love my house. You know what I mean, I love being here, it's my home, and that's something. I do have a couple of statues of Ganesha, He's my deity. He is the remover of obstacles, which are usually ones own fears and desires. something an "Ennis" like me should take to heart.
