This week India's renowned spiritual leader, Her Holiness Sri Mata Amritandamayi, better known as 'Amma' or 'mother', makes her annual pilgrimage to the UK.
Although she comes from a Hindu tradition, she teaches that all religions are equal and she's the first Hindu leader to have inaugurated women priests. Last year her humanitarian work won her the prestigious Gandhi-King Award for Non-Violence. She's considered by the millions of devotees in her own country to be a living saint and sage. In her extensive tours around the world, she's given her special blessing, in the form of a hug, to an estimated 21 million people.
