The bija mantra HRIM: To access the spaciousness of the Heart
BIJAS A "bija" is a mystical seed sound of the Tantric tradition and is like a seed that is planted into the fertile soil of our psyche. With awareness and repetition this "seed" blossoms into an entire field of spiritual energy within our being: potentially images, sensations, sounds, and insight into an aspect of Beingness. We then can embody this aspect of being, if we so choose, and have it inform our life. A bija has no literal meaning; it embodies an experience.
HRIM (pronounced HREEM) The bija Hrim is one of the most common bija mantras. It is composed of the sound 'H', which is prana and space; 'R', which is fire and light; the sound "EE , which indicates energy, desire, and movement; and "M" which is the state of dissolution or the return back to source energy.
“Hrim” is the resonance of the "hridaya", or heart, but the heart on ALL levels: it is the heart of the Goddess, the heart of the Universe, the emotional heart, and our own physical heart organ. It is the spaciousness of the Universe and the spaciousness we hold in our own being which is accessed through the heart. This vibration, HRIM, is thought to be always resounding in our heart.
SAKTI In Tantra, the source of the Universe is a feminine energy called Sakti. Primal Sakti or the first energy of the Universe splits or manifests into a variety of channels or dimensions. One form of Sakti is the energy of Bhuvaneshwari which is the material, physical cosmos. She is the space that holds the cosmos, that permeates it, and that sustains it. The Universe is the body of Bhuvaneshwari! Her mantra is HRIM.
You can chant "HRIM" silently or "Om Hrim namaha". Tantric mantras are generally chanted internally, the idea being that an "alchemical" reaction needs to take place within ourselves. We need to build this spiritual power within ourselves and not let it "leak" out. You could whisper it if you prefer hearing your own voice when you are practicing privately. The key to building spiritual power within the Tantric tradition requires that you keep the practices secret. You are the protector of these sounds.
As you meditate on this sound, allow yourself to feel the energy of the Universe, Sakti, breathing through you.
