When the sun sinks behind the western skyline, when shadows thicken and merge in the enveloping gloom, when from the horizon the carpet of stillness spreads across the twilit world, a simple ritual is performed in scores of ashramas and in thousands of homes in adoration of a being known to the world as Sri Ramakrishna. In a special room or corner of a room set apart for his unseen presence, incense is burnt and lights are waved, and often there is group singing of songs and hymns of praise and supplication.
