Bija MantrasThe word Bija means a seed and describes a mantra which is usually of one syllable. There are many tantrik 'dictionaries' of the matrikas which indicate their significance as well as the meaning of the bija or seed mantras. This section below draws information from the Bhutadamara(BD); the Varnanighantu (VN), alleged to be part of the Rudrayamala; and the Uddharakosha (UK), ascribed to Dakshinamurti. Longer mantras are often formed from a concatenation of these bijas. The table below is not exhaustive, there are many more bijas.
