Giver of Salvation - MAHA MERU
The Maha Meru, a 64-triangle 3-dimensional configuration incorporating both the Siva and Shakti principles, has 64 sakti yoginis within it. Anyone worshipping the Maha Meru can get the blessings of all shakti yoginis. This leads to the path of salvation.
The Maha Meru and Sri Gayatri are found in the same sannidhi.
