Hrim is a seed mantra. It represents invisible sound, infinity and divine energy of 24 Tirthankars. Maditating Hrim, one experiences sublimating energy of 24 Tirthankars.

The mantra is pregnant with the vowels and consonants of Sanskrit language. A is the first alphabet and H is the last alphabet of Sanskrit. In this mantra, sound of all vowels and all consonants are present.

It is an ancient, miraculous and supreme mantra of all mystical seed mantras. Even the kundilini (hidden serpent like dormant energy) can be awaken by meditating on this mantra. Ultimately with the help of this mantra, its vibrations and its experiences, one can liberate himself/herself from the cycle of birth and death.
