I listen to many different paths playing mantras online on Youtube.... Just type in protection mantra or healing mantra in the search bar and you get many to choose from... Personally I like to google the energy source so I know who I'm requesting my intention from...For example: Mahakala or White Tara mantras for protection.... on and on...
Here is a mantra mix that I made for fun and play all the time ...
