Yantra can be simply explained as a divine geometry. There are many yantras. The most powerful yantra is called as Sri Yantra. It is also called as Sri Chakra.
This has been worshipped in a specified manner from time immemorial in India. This is a symbol of both the Universe and its cause.
Sir John Woodroffe (1865-1936) in his book, Shakti and Shakta has explained it in detail thus:
It is composed of two sets of Triangles. One set is composed of four male or Shiva triangles called Shrikanthas denoting four aspects of evolved or limited Consciousness-Power, and the five female or Shakti triangles denote the five vital functions, the five senses of knowledge, the five senses of action, and the five subtle and the five gross forms of matter.
These two sets of triangles are superimposed to show the union of Shiva and Shakti. As so united they make the figure within the eight lotus petals in the full Yantra. Outside these eight lotuses there are sixteen other lotuses. There are some more lines which is called as Bhupura. It serves as a fence.
The Sri Yantra should not be hanged on a wall. It must be kept flat or horizontal to the ground and must be worshipped daily with offerings. It should not be drawn on ground, wall, or plank.
Even there is a prescribed way to draw the Yantra to the correct proportion.
Sri Chakra drawn on a plate, foil or disc of gold, silver, copper or any other material can be worn on person as talisman.
Sri Chakra can be worshipped by one and all irrespective of religion, caste or creed, sex or age, young or old, high or low, the learned or ignorant and the rich or poor.
The secret of Sri Yantra worship is that It will bestow wealth, health and above all salvation.
We may find Srichakra in all states of India, namely Andhra Pradesh, Assam, Gujarat, Himachal Pradesh, Kerala, Karnataka, Madya Pradesh, Pondicherry, Tamilnadu, Uttar Pradesh etc.
Swami Pranavananda has visited almost all the places where Sri Yantra has been installed. He has given details of one hundred and eighty places in detail in his fantastic book titled ‘A Treatise on Sricakra’
It is interesting to note that Sankara the great master of advaita visited Kashmir and built a temple there on a hillock. He has installed one Srichakra also there after which the capital of Kashmir was named Srinagara another name of Srichakra.
Knowing the full details of all the one hundred and eighty places where these capsules of cosmic energy were installed will inspire each and every one.
Whoever is interested in Sri Yantra should also read the findings of the scientist Alexi Kulaichev.
In my next article I will explain the scientific findings as well as the Scriptures version.
