Hrim Smara, Yoni, Lakshmi (standing for the syllables klim, hrim and srim) in the beginning of a mantra to Devi. http://acharya.iitm.ac.in/mirrors/vv/literature/sankara/sound4.html In the context of Kadi Mantra, HRIM means the following. R is the waking state of the phenomenal world; I is the cosmic sound, responsible for creation of the universe and represents the dream sleep state; M is the deep sleep state; thus, the Mantra stands for the three states of consciousness. Waking state is akin to the phenomenal world; dream sleep is akin to creation, when in our mind we create disparate images; Deep sleep state is when we are oblivious of the phenomenal world and merge with our god and remain in a temporary state of bliss. Elsewhere in this article, you will see these states correspond with AUM. http://www.bhagavadgitausa.com/TANTRA.htm Hrim (maya-bija, Sakti),
