Question: What is the significance of seeing a very blue light during meditation?Sri Chinmoy: A blue light is the light of Infinity. To see blue light around yourself or someone else means that your inner being is responding to the vast Infinity, that your spirituality is mature and has entered into your inner and outer existence. This is a very good experience, a very high experience. White light is spirituality; blue light is also the light of pure spirituality, the light of the Infinite. To see blue light around some spiritual Masters, for example, Lord Krishna, means that blue is their predominant colour, although some spiritual Masters have all colours in their aura.
