commemorates a day when Colonel Olcott [one of the founders of the Society, along with Madame Blavatsky] was dying, and was trying to choose a successor to head the Society. Several rishis [immortal sages] materialized in the room, were seen by others as well, and told Col. Olcott to nominate Annie Besant.
It is also Bishop Leadbeater's birthday. Once, when Leadbeater was sitting near Mme. Blavatsky, a letter from rishis in the Himalayas suddenly materialised. The letter said that he should go to India to work with the Theosophical Society. He did go, and was granted jnana-drsti -- second sight. He could magnetise jewels to make rakshas [raksha = protection; so, jewels which protect their wearers], and could see nature spirits building the leaves of the trees.
