By remaining silent or by speaking less, not only do we learn control over what we speak, we also conserve our life energy. Restraint of speech is only external silence whereas silence of mind is the inner and true silence. The true and complete silence is when both mind and voice are completely silent. The great rishis and spiritual masters adopted silence as an integral part of their lives during their penance and carried out intense spiritual practices. By remaining silent they could stay away from worldly, materialistic affairs and attain the inner peace. (Akhand Jyoti January-February 2016)
