Indian culture has been among the few cultures on this planet – if you look at it in terms of its geographical size, probably the only one of such size – where for thousands of years, the whole population was focused only on the ultimate wellbeing of the human being. The immediate, material wellbeing was just handled as a small part of one’s life.
Indian culture is the most complex and colorful culture on the planet. You will see, the way people look, their language and food, their way of dressing, music and dance, everything is different every 50 or 100 kilometers in the country. One place where you can really see the complexity of this culture is the Kumbha Mela.
Before you attempt anything that is considered as a mystical process, it is very important to stabilize the five fundamental elements within you. These are known as pancha bhutas or maha tatwas in the yogic science. The body, the very earth, the universe, and the cosmos, all are just a play of five elements. The body’s composition is such that most of it is water. Then there is earth, air, fire, and the rest is akash or etheric space.
There are many aspects to the usage of vibhuti or sacred ash. First of all, it is a great medium to transfer or transmit energy, and it has an ability to help direct and control the energy body. Apart from that, there is a symbolic significance to applying it on the body. It is a constant reminder of the mortal nature of life – it is like you are always wearing mortality on your body.
