Learn The Other Way Round. Why Other Way Round? To have a better understanding. To get a complete picture. Start it and everything will change. Great men always think the other way round. Gautama Buddha Done it. Osho too took the same route. Even Jesus Christ is not an exception! Look at this: From ‘Glob’ we got ‘Blog’. Look at the ‘Dog’ and the ‘God’ will emerge from it!
