Are the chakra tests valid?
Assuming you mean the online chakra tests, I'll have to say no. Chakras are essentially energy and you can't reallyhave your energy read from a test online. Well, you can but the results are rarely accurate.
Is it good you have active Chakras?
If you did an online Chakra test, you might not know if your Chakras are actually actve or inactive. If you do have active Chakras, that's not bad. Some people can advance quicker and understand things more easily. Having active and open Chakras isn't anything to worry about and some people's Chakras are like that right off the bat.
Different spirts hae different personalities. One Angel can be insghtful ad helpful where anoter one can be malevolent and angry. It's hard to say exactly hw each spirit wll act. Everyne has their own experiences with them.
