Some interesting information:
In many world religions, disciples have traditionally shown their respect by kneeling at the feet of their guru. Even today, children in the villages of India continue an age old tradition of massaging their parents legs and feet as a symbol of service, humility and love. Many spiritual traditions believe the body and soul are connected to and even embodied in the soles of the feet. Buddha’s footprints for example have long been used to represent his entire being. And even today, Vishnu’s footprints are worshipped in temples and other holy sites across Asia.
In many cultural and spiritual traditions, seekers kiss, wash, or worship the feet of their spiritual teachers. The Bible contains thirty three references to this phenomenon, including the gospel scene in which Mary Magdalene bends to wash Jesus’ feet with her tears, and olive oil as a symbol of her deep respect for him, and as a form of penance. Western experts often adopt a pragmatic and cautionary approach to the role our feet play in our lives. According to a recent report by the American Podiatric Medical Association. “Your feet mirror your general health. Such conditions as arthritis, diabetes, nerve and circulatory disorders can show their initial symptoms in the feet – so foot ailments can be your first sign of more serious medical problems”.
Because the feet work in conjunction with the legs, knees, hips and back. Foot problems can lead to muscle tension elsewhere in the body. Especially in the back, neck and shoulders. This can intensify fatigue and irritability.
