New Delhi, Aug 1 - Shivi Dua, a computer software professional, switched professions when her daughter was diagnosed with asthma in 2000. She started practising Reiki -- and treated her daughter with it.

A few years on, in 2005, Dua moved to a new and powerful form of alternative healing -- Theta healing, which cured her daughter permanently.

By then, Dua had become popular as a healer across the country. 'In 2007, I decided to write about my experience as a theta healer and explain the ways to heighten human consciousness so that it is in tune with the subconscious. When both these states are taken to a meditative level, the brain begins to emit positive theta waves to connect to the higher cosmic energy -- which is the basis of theta healing,' Dua told IANS.

The result of a three-and-half months of hard work was a slim volume 'Let The Power Be With You' -- a primer for positive living which is the first step to theta healing.

Published by Wisdom Tree, the book was released by danseuse Sonal Mansingh at the Oxford Bookstore in the capital Friday.

'The people who had received treatment from me wanted me do something for the conscious mind because I usually treat the subconscious. The conscious mind needs counselling so that both are in tune and my patients wanted the counselling sessions to be documented,' Dua said.

Theta healing, says Dua, involves taking brain waves to a new level so that they tune the natural frequency of the body to connect to cosmic forces. The treatment is based on the premise that 'everything emanates from within one own's self'.

'The brain emits four kinds of rays -- alpha, beta, theta and gamma,' Dua said, adding the theta waves (4-7 cycles per second) usually occur in sleep or in the highest state of meditation.

In this state, human minds are most receptive to information from a higher dimension.
