Thousands of years ago spiritual secrets were taught to disciples in remote caves and deep in jungle areas but nowadays same secrets are taught very comfortably in air-conrditioned rooms in good hotels. Those days to communicate with the Guru one has to travel hundreds or thousands of miles but now we have cell-phones and sms .Those days Gurus contacted disciples thru telepathy but cell-phone makes it easier. Welcome to the 21st century where everything is possible.
