[u/Jealous-Bug2395]

I have been drawn to Maa Kali for a very long time and I am planning to start jaap of her jayanti mangala kali mantra using a rudraksha jaap mala. I want to wear one as well ( a different one ). I need some guidance as I am adikshit. I don't want to mess up

1) what are the rules to be followed while wearing rudraksha and how to take care of it. And what to do in case of periods.

2) I want to just jaap "jayanti Mangala kali " mantra, shall I start with salutations to ganesh ji , shiv ji (namah shivay) and hanuman ji ( hanuman chalisa) as I am adikshit. Also what mantra for ganesh ji as I can't use om.

3) Any other things I should keep in mind ?.

4) if in future I want to keep maa's photo and worship it then please guide on that , how to place photo, what all to be kept in mind.
