There are many Ayurvedic doctors who wear saffron robes and look more like monks than practitioners and there are others who look normal. Whom should you chose?
Those who look spiritual outside might not be really spiritual inside. Those who look as normal may be very spiritual from inside. Spirituality does not lie in how a person looks or what he is wearing. Spirituality lies in the purity of heart and mind. Moreover, there is no hard and fast rule that an Ayurvedic practitioner should be spiritual in order to be successful in healing disease and promoting health.
However, for a holistic Ayurveda treatment approach, it helps for an Ayurvedic doctor to have a spirituality inclined mindset.
