Anthropological studies on causality in South Asia in the past decades have focused mostly on local idioms of 'mis fortune', with very little attention being paid to ideas of 'fortune' and 'luck'. This article, based on fieldwork carried out among astrologers and their clients in Banaras, shows that astrology provides an ideological framework for the conceptualization and management of fortune in present-day urban India. According to astrologers' analyses of horoscopes, 'destiny' (bhāgya, lit. 'allotted share') is conceived as a form of wealth acquired at birth that can be augmented or diminished as a result of planetary influences and personal choices. The author suggests that, beyond the Sanskrit tradition, the semantics of destiny can be linked to decisionmaking processes and values of achievement that mark the lives of middle- and upper-class families in contemporary India.
