Practise asanas (postures) to strengthen and heal your eyes and head, ie brain, pituitary and pineal glands
The first words of the Dhammapada, the teaching of Buddha says “all that we are is the results of our thoughts. With our thoughts, we make the world. If we think in a negative way then that negativity will follow us, as sure as the wheel follows the ox that draws the cart.
If we think in harmonious ways, happiness follows us as sure as our own shadow, never leaving us.”
