This contains the energetic essences of a few mantras from hindu and buddhist traditions.
Om Namah Shivaya
The Gayatri Mantra
Om Mani Padme Hum
Namo Amituofo (Namo Amithaba Buddha)
The core essence of things represents the purity of what a concept represents.
These can propel you on a path of serious mental and spiritual growth.
Of course, this goes far deeper and more complicated than described.
But you as a seeker will discover these things, as you keep on the path.
I believe it contains the essence of the Hare Krishna mantra as well.
