“Jugupsa is an expression of the protective intelligence inherent in every individual. There is a principle central to Ayurveda, the healing science of India, which states that until our bodies are well purified, we tend to crave the foods and activities that entrench and even aggravate our imbalances. We will be attracted to the things that are bad for us.
It is only when purification has restored the natural balance that we begin to be drawn to that which is beneficial while turning away from that which is harmful. For example, if a lit cigarette were held next to a baby’s nose, it would squint and withdraw for the smoke. This natural impulse arises from the inborn capacity of clean lungs to discriminate between what is harmful and what is healthy.
As a result of physical purification the body’s protective instincts become fully awakened and alert. Unhindered by the influences of entrenched toxins, they become engaged in the business of warning us away from foods, drinks and activities that are detrimental to our health. And just as important our immune systems can now work at their optimum level, improving the body’s defense against disease.”
Rev Jaganath Carerra, from his book, Inside the Yoga Sutras
