How have Hindu festivals been integrated into aspects of everyday life in Indian?

Explanation:

Hindu festivals are combinations of religious ceremonies, semi-ritual spectacles, worship, prayer, lustrations, processions, music and dances, eating, drinking, lovemaking, licentiousness, feeding the poor, and other activities of a religious or traditional character. The original purpose of these activities was to purify, avert malicious influences, renew society, bridge over critical moments, and stimulate or resuscitate the vital powers of nature (hence the term utsava, meaning both the generation of power and a festival). Because Hindu festivals relate to the cyclical life of nature, they are supposed to prevent it from stagnating. These cyclic festivals—which may last for many days—continue to be celebrated throughout India.

Such festivals refresh the mood of the participants, further the consciousness of their own power, and help to compensate for their sensations of fear and vulnerability concerning the forces of nature. Such mixtures of worship and pleasure require the participation of the entire community and create harmony among its members, even if not all contemporary participants are aware of the festival’s original character. There are also innumerable festivities in honour of specific gods, celebrated by individual temples, villages, and religious communities.
