The article analyzes the social aspects of Hinduism as a combination of not only religious, but also mythological, legal and ethical concepts. They form, on the basis on which the social life of Indian society is largely organized. The author’s analysis of the historical development of Hinduism shows that, despite the absence of a rigid organizational structure, it has an internal unity at the social, ideological and religious levels. Hinduism is united in a whole by sacred texts and the Pantheon of Gods, recognized by almost all its trends and schools, as well as the faith in karma — the causal relationship between the actions of an individual in past incarnations and his fate, character, position in society in the current incarnation, and reincarnation. The cornerstone of both the faith and the social component of the Hindu doctrine is the concept of classes and castes, which denote separate groups whose members have a common professional occupation, do not marry other groups, and do not even share meals with them. The article considers the hierarchy of classes that originated in India in the Vedic period, as well as the principles, primarily professional and regional, of the formation of modern castes.The author analyzes a set of religious prescriptions and cult practices that regulate the daily life of Hindus, the ritual side of Hinduism associated with the most significant events in human life. Special attention is paid to new practices of “redemptive rites”, including asceticism, fasting, various methods of mortification of the flesh, and redemptive gifts. It is noted that the essence of Hinduism is not limited to its religious and ideological content. An organic integral part of it is a number of social institutions, legal and moral norms, social institutions and cultural phenomena. In this regard, Hinduism is not only and not so much a religion, but a way of life and holistic behavior, which can also have its own spiritual practice.
