The Dasa Mahavidhyas step in to transform this painful grueling existence into a far simpler and peaceful one if we try to understand and realize their presence better. The Goddess who steps up at this hour of need among the great Mahavidhyas is Tara, the Mother who is known to transport us from the powerful shackles of trouble to a higher realm of peace.
Mythology describes that during the churning of the ocean, when the Halahala overflowed and threatened to destroy the world, Lord Shiva had the presence of mind to consume the deadly poison that turned his throat blue. What is unknown is that Shakti in the form of Ma Tara calmed down his burning throat by feeding Him her life giving milk. This story gives a glimpse of the power of Lord Shiva to take control of the universal deluge into Himself to save all life and Ma Tara protects all living creatures from the ocean of poison through her power of creation.
Here, the "ocean" or the "poison" or "halahala" can be interpreted as the depth of sorrow or fear our worldly problems bring with them, describing the nature of the problem to be humongous or as deep as the ocean or as noxious as poison. Ma Tara symbolizes that which saves us from all such harm. She takes up three forms, each of which symbolize a state of mind.
She appears as Ughra Tara, in the fierce aspect similar to Kali who walks on corpses and collects all the ignorance of the three worlds into her cup made of the human cranium. Her vibrating war cries surge ahead and kill the pale noise of ignorance in one sweep. She appears as Nila Saraswati or the blue Goddess of sweet sound that flash bright as a lightening and destroy all the darkness around. She appears as Ekajata, representing the one who has channelized all her sound energies into one single goal of creation. Tara therefore is represented as the White Goddess, full of knowledge and full of purity who saves us from our own evils.
Lets dive into the beauty of this representation. Tara is the Mother who is invoked to help one self reduce the noise within and better the quality of thought and purify the mind. Tara, represented as the guiding light who scales across the universe, is the protector who eases the dense cloud of illusion that surrounds the bhakta. She is the primordial sound Om, that which is necessary for creation and the one who purifies the sound that is generated from the being. Tara is the Goddess who is invoked when the bhakta has reached the lake of nectar and needs her boat, Tari, in order to cross the divine lake to reach the Seat of Lalita, the mansion of the Great Goddess who rules the Sri Chakra.
The Dasa Mahavidhyas looks to be a step by step approach towards one's own spiritual progress where Tara represents the power to kill ignorance, and the power to purify the mind. Tara, turns into the navigator of universe within the spiritual mind when the bhakta completely surrenders to her. Bestowing the boon of sweet words, she helps the Bhakta to cross the lake of nectar to reach the Gates of the Goddess Lalita. Tara, the white Goddess, in her purity is the guiding principle that kills all ignorance and delivers us to a higher realm of peace.
