Best Kali Mantras For People Facing Lot Of Problems, Hav

After an interesting discussion, Cure For Black Magic ?

I am doing Maha Mrutunjay mantra (still perfecting the pronunciation), once in morning, one before bed, 108 times each. This is great for scardy cats and the unknown just scares me!

Also interested in Kali Mantra. Really like this aspect of G-d since it makes you face the dark side of humanity that we all tend to shun.

There are so many Kali Mantras. Please tell which Kali Mantra is best for those
- who are facing problem on many fronts
- have lot of ill-wishers
- has difficulty removing anger/sadness from past
- who need help creating and establishing personal boundaries

 

Ok, I understand one has to be careful with Kali puja because results are swift and sometimes (initially) unpleasant.

From personal experience can you recommend simply Kali puja mantras, especially for a beginner facing all these problems (or rather, my Dad is facing lot of problems, wish to help him)
