(Sorry if the flair is incorrect the others didnt seem to fit my question!)
So I have this small box ive been wanting to make a travel altar for Apollo but would it be fine to have in my locker i have in my schools band hall?
Theres no way I could probably clean or cleanse the locker and no way I could have just the altar in there alone
I am planning on making a main altar in my home where I can probably cleanse the area but for the travel altar is it fine to have it in such an unclean space?
Theres also no way I could probably cleanse myself to pray while at band the student bathroom is a decent walk outside the band hall and id have to ask to go everytime
Are their different rules for praying at travel altars or am I over thinking this whole thing?
