On the Bhuvaneśwari jayantī I want to write something about her famous and very significant mantra ह्रीँ (hrīm̐), which is sometimes called Mahāmāya–bīja (the seed syllable that includes all dimensions). According to the Vedas, the first sound of the original yajña and creation was the famous praṇava Om. Out of it three mātras (अ – उ – म) three worlds arose, it is also a form of anāhata–nāda creating or absorbing the creation. The practice of nāda is very significant for laya–yoga. However, each tradition has its own forms of praṇava, for example, in the Śаiva–sampradāya it is the bīja हुं (huṃ), in the Kaula–sampradāya it is the bīja ऐँ (aim̐), in the Trika tradition it is the bīja सौः (sauḥ), and for the Śаktas the praṇava will be ह्रीँ (hrīm̐). Since so many do not at all distinguish the concept of tantra with śakti–upāsanā, in India praṇava is often associated with tantrism. Thus, the Goddess Bhuvaneśwari is the Mother of all worlds, of different dimensions (bhuvanas) and is very significant for Śaktism in general.
