Our Puranas, Itihasas say that there were rishis (sages) who did thappas by meditating for years without eating food or drinking water.
ever wondered that how is this possible, without food we may survive for few days or weeks but without water not even a whole day.
so many concluded it as completely false, it was just fancy stories etc.
but here they got an answer from the land of sages Bharath. Prahlad Jani also known as “Mataji” age of 81 from Gujarath state has been living since 70 years without eating food and drinking water.
then what is his sourse of energy? he gets energy from live god “Surya Narayana” . he used to observe sun rays daily in early morning and used to do meditation and yoga.
