The result of mantra japa can be compared with that of a stone thrown into a pond that create waves, but goes into the deep. Mantras has the power to experience the depth of the mind, by creating waves at the surface level.
The practice of mantra japa results in expressing one’s own impressions of the mind as it starts diving into the depths. Every mantra has “bija” mantra or bijaksharas. They are otherwise called as the seed included in each mantra.
Most of the mantras starts with “AUM”. There are some occasions where “Aum” is chanted three times before the starting of slokas, comprised of mantras. Some of the bija mantras are: Aum, Ham, Yam, Ram, Vam, Lam. Bija mantra can otherwise be called as mystic sound generated through the chanting of mantra.
In spiritual practice, mantra japa helps to gain awareness and increase concentration. It helps a lot to concentrate on one’s “ishta devata”, the favorite deity, thus helping to meditate by sitting in a fixed posture. Mantras are part of tantric tradition that deals with the awakening of the consciousness lying within every human being. It is also known as the awakening of kundalini power by awakening the chakras. Bijaksharas are formulated in such a way to awaken these chakras so that the individual consciousness is expanded to become universal consciousness.
Mantras are said to have revealed in the consciousness of sages before ages. And among these, Bija mantra is the first syllable in each mantra. Each bija mantra has association with its mantra. For example, Lord Shiva’s bija mantra is “hraum”, “dum” is Durga’s mantra and “kreem”, of Kali. It is believed that the subtle forms of these mantras exist in this cosmos. Bija mantras are beyond the intellectual understanding and usual grammatical rules in any language.
Repeated, concentrated mantra japa takes the practitioner to various planes of consciousness by experiencing the inner silence. In tantric tradition, chakras in the human body has immense important in awakening the consciousness. Vibration of mantras touch these chakras by making changes in the mind of the practitioner.
