A Yantra is an instrument for the promotion of meditation and inner visions. Basically a creation-myth, it exploits the connection between external and internal actuality and allows cosmic psychic events to be brought to bear upon the resultant unity. Whitney’s film Yantra was produced entirely by hand between 1950 and 1955. By punching holes through cards with the help of a needle, Whitney was able to produce images of rich complexity. These punched grids were coloured with an optical printer so that the basic structure of the holes could be filmed. Yantra was initially released as a silent film.
