Portrait of Sadhu Naga Baba. Varanasi,India. Naga Sadhus of India are known for their peculiar religious practices, but perhaps none are more shocking than the art of penis bending and penis aerobics displayed by the Hatha Yogis. This Baba performs a yogic exercise which goes by the name of chabi, meaning 'key'. The aim of this exercise is not just retention of the sexual energy, but forcing it back, and 'up'.Put in simplistic yoga 'mechanics': keeping the penis down so the kundalini may rise.
Naga Sadhus are renouncers who have chosen to live a life apart from or on the edges of society in order to focus on their own spiritual practice. The significance of nakedness is that they will not have any worldly ties to material belongings, even something as simple as clothes.
