Reference to question raised by Alan earlier regarding light in meditation
We have a posting from Om Lala - which may be of interest:-

>From VIVEKANANDA A BIOGRAPHY by Swami Nikhilananda: At this time
(childhood)
he (Swamiji) daily experienced a strange vision when he was about to fall
asleep. Closing his eyes, he would see between his eyebrows a ball of light
of changing colours which slowly expand and at last burst, bathing his whole
body in a white radiance. Watching this light he would fall asleep. Since
it was a daily occurrence, he regarded the phenomenon as common to all
people, and was surprised when a friend denied ever having seen such a
thing.
Years later, however, Narendra's spiritual teacher Sri Ramakrishna, said to
him, "Naren, my boy, do you see a light when you go t sleep?" Ramakrishna
knew that such a vision indicated a great spiritual past and an inborn habit
of meditation. The vision of light remained with Narendra until the end of
his life though later it lost its regularity and intensity.
