Arms of a Cross mark doorway into the square setting out stable foundations on the earth. Each door also is a doorway out into the regions of the cosmos. Through these you enter the model gradually moving into the central bindu via the 9 layers, or chakra. Each of these 9 levels have a distinct shape, name and are associated with a number of aspects of the Great, or Supreme, Mother.
In essence, you enter the constructs of the physical world and our bodies, bound within it, to ultimately experience the union of Shiva and Shakti in the Point of unity at the centre, the highest peak of the mountain.
Every yantra has a mantra(s), tones in ancient Sanskrit that activate and invoke the power of the geometric model. During Sri Yantra puja about an hour of these are chanted by the swami. The presiding deity of the Sri Yantra is Maha Tripura Sundari, the Great Mother. Each layer radiating out from the bindu has mudras, or deities, residing within them. This is describe in the Sri Devi Khadgamala Stotram, a hymn to the Divine Mother, which 'bestows a garland of swords upon those who recite it, symbol of the energy that enables us to transcend attachment and rise on the spiritual level'. This Sanskrit stotra is a progressional worship of the many Goddess forms within the Sri Yantra and is considered as the highest form of worship to the Devi (Godess).
This is a simplified description of a multi-step, sacred ceremony that is many centuries old, with layers of rich symbolism. Doing a full worship is extremely difficult to do properly and few can do it!
The Sri Yantra puja is said to remove all negative things from your life.
Experiencing the Sri Yantra Puja
This summer I was honoured to be invited to participate in a Sri Yantra Puja held in the Adhya Shakti Mataji Temple in Uxbridge, UK. It was the first time Acharya Umesh Tiwariji (Instagram: Acharya Shri Umesh Tiwari) had visited the UK. He is a noted master trainer in the Sri Yantra Sadhana from Shrishri Vidhyadham.
You can experience the mantras of the Sri Yantra Puja by Acharya Umesh Tiwariji in the youtube video below. The complete, live experience is naturally more 'powerful' and Acharya Umesh Tiwariji will be returning to the UK, as well as travelling to other countries. I highly recommend the experience and will certainly be repeating it myself.
