Descent of Krishna into the Physical

The lights indicate the action of certain forces, usually indicated by the colour of the light. Whitish blue is known as Sri Aurobindo's light or sometimes Sri Krishna's light.

The meaning of blue light depends on the exact character of colour, its shade and nature. A whitish blue like moonlight is known as Krishna's light or Sri Aurobindo's light - light blue is often that of Illumined Mind - there is another deeper blue that is of the Higher Mind; another, near to purple, which is the light of a power in the vital.

24th November 1926 was the descent of Krishna into the physical.
Krishna is not the supramental Light. The descent of Krishna would mean the descent of the Overmind Godhead preparing, though not itself actually, the descent of Supermind and Ananda. Krishna is the Anandmaya; he supports the evolution through the Overmind leading it towards the Ananda.
