Where do you face when chanting mantra

[Guest guest]

I bought 3, 4 ,6 and 8 mukhi rudraksha for my niece fore education. Where should

I face when chanting the mantra for knowledge?

 

And what mantra should I recite that will help her in her studies since I'm the

one chanting it for her?

 

And I also got myself rudraksha of 2 ,4 , 6, 7, 9 ,10, 13 and 17 with a

vashikaran locket?

 

For lovelife where should I face while chanting the mantra? ANd what is the

mantra for vashikaran locket? How do you chant both of them to make it work?

There's a specific person involve
