Yantra can easily be explained as a divine geometry. There are many yantras. The most powerful yantra is called Sri Yantra. It is also called Sri Chakra.
This has been worshiped in a certain way from early 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 consists of two sets of triangles. A set consists of four male or Shiva triangles called Shrikanthas which denote four aspects of developed 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 senses of knowledge. five subtle and five gross forms of matter.
These two sets of triangles are delineated to show the Shiva and Shakti unions. As so united, they make the figure within the eight lotus leaves throughout Yantra. Outside of these eight lotuses are sixteen other lotuses. There are some more lines called Bhupura. It works like a fence.
Sri Yantra should not be hung on a wall. It must be kept flat or horizontal to the ground and must be worshiped daily with offers. It should not be drawn on the ground, wall or plank.
There is also a prescribed way of drawing Yantra to the right proportion.
Sri Chakra drawn on a plate, foil or slice of gold, silver, copper or other material can be worn in person as a talisman.
Sri Chakra can be worshiped by anyone and everyone regardless of religion, caste or creed, sex or age, young or old, tall or low, the learned or ignorant and the rich or poor.
The secret of Sri Yantra worship is that it will provide wealth, health, and above all salvation.
We can 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 places where Sri Yantra has been installed. He has given details of one hundred and eighty places in detail in his amazing book entitled "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 hill. He has also installed a Srichakra there, after which Kashmir capital is called Srinagara another name Srichakra.
Knowing all the details of all the hundred and eighty places where these cosmic energy capsules were installed will inspire everyone.
Anyone interested in Sri Yantra should also read the results of researcher Alexi Kulaichev.
In my next article, I will explain the scientific results as well as the script version.
