Shiva Kavach Mantra
From here -
I listen to the maha mrutyunjaya and several other Shiva slokas. Tuesdays it is the Subramanyaashtakam or the Kanda Sashti kavacham. Wednesdays and its time for Ganesha Pancharatnam. Thursdays and without a doubt, it is Hanuman Chalisa (MSS version here). Fridays are for listening to this particular version of Mahishasura Mardhini Stotram. I have yet to make a habit for Saturday and Sunday mornings, but perhaps from this week, I will.
