These discourses were bestowed to the girls of Vivekanand College, New Delhi, by mystic master Anandmurti Gurumaa. We eat food to strengthen our body, but what do we do to nourish our brain? Are we aware that we hardly use a tiny fraction of its total potential? Gurumaaji elaborates on 2 powerful methods which enhance brain functioning. Yog Nidra is an ancient technique of meditation which involves multi-level relaxation. When we learn how to relax deeply, our receptivity, concentration and learning power increase tremendously. This technique allows us to tap into our subconscious mind and access its immense potential for transformation. Our eyes are extensions of our brain. The technique of Tratak, via the route of the eyes actually activates our pineal gland, which corresponds to the third eye. This means that it enhances our power of intuition, concentration and receptivity to higher knowledge from within.
