There are many Hindu Festivals celebrated throughout the world but mainly in India and Nepal. These festivals include worship, offerings to deities, fasting, rituals, fairs, charity, celebrations, Puja, etc. The festivals mainly celebrate events from Hindu mythology, changes in season, changes in Solar System. Different sects celebrate different festivals but festivals like Diwali, Holi, Shivratri, Raksha Bandhan, Janamashtmi etc. are celebrated by the majority of Hindus.
Hinduism can be divided in following ages
The origins of Hinduism are unknown but the earliest traces of Hinduism come from Mesolithic in the sites such as the rock paintings of Bhimbetka rock shelters dating to a period of 30,000 BCE or older, as well as neolithic times. Some of the religious practices can be considered to have originated in 4000 BCE. Several tribal religions still exist, though their practices may not resemble those of prehistoric religions.
According to one view, the Varna, which later transformed into caste system during the British rule, shows how strongly many have felt about each person following his or her dharma, or destined path. Many Hindus say it goes against the true meaning of dharma. However, Varna plays a big role in Hindu society. It's later transformation as Caste system by the British rule of India lost favor and became illegal after the independence of India.
Puja (worship) takes place in the Mandir (temple). Mandirs vary in size from small village shrines to large buildings, surrounded by walls. People can also visit the Mandir at any time to pray and participate in the bhajans (religious songs). Hindus also worship at home and often have a special room with a shrine to particular gods.
Temple construction in India started nearly 2000 years ago. The oldest temples that were built of brick and wood no longer exist. Stone later became the preferred material. Temples marked the transition of Hinduism from the Vedic religion of ritual sacrifices to a religion of Bhakti or love and devotion to a personal deity. Temple construction and mode of worship is governed by ancient Sanskrit scriptures called agamas, of which there are several, which deal with individual deities. There are substantial differences in architecture, customs, rituals and traditions in temples in different parts of India. During the ritual consecration of a temple, the presence of the universal all-encompassing Brahman is invoked into the main stone deity of the temple, through ritual, thereby making the deity and the temple sacred and divine
The Bhakti (Devotional) school takes its name from the Hindu term that signifies a blissful, selfless and overwhelming love of God as the beloved Father, Mother, Child, or whatever relationship finds appeal in the devotee's heart. The philosophy of Bhakti seeks to tap into the universal divinity through personal form, which explains the proliferation of so many gods and goddesses in India, often reflecting the singular inclinations of small regions or groups of people. Seen as a form of Yoga, or union, it seeks to dissolve the ego in God, since consciousness of the body and limited mind as self is seen to be a divisive factor in spiritual realization. Essentially, it is God who effects all change, who is the source of all works, who acts through the devotee as love and light. 'Sins' and evil-doings of the devotee are said to fall away of their own accord, the devotee shriven, limitedness even transcended, through the love of God. The Bhakti movements rejuvenated Hinduism through their intense expression of faith and their responsiveness to the emotional and philosophical needs of India. They can rightly be said to have affected the greatest wave of change in Hindu prayer and ritual since ancient times.
The most popular means of expressing love for God in the Hindu tradition has been through "puja", or ritual devotion, frequently using the aid of a "" (statue) in conjunction with the singing or chanting of meditational prayer in the form of mantras.
Devotional songs called bhajans (written primarily from the 14th-17th centuries), kirtan (praise), and arti (a filtered down form of Vedic fire ritual) are sometimes sung in conjunction with performance of puja. This rather organic system of devotion attempts to aid the individual in connecting with God through symbolic medium. It is said, however, that the "bhakta", through a growing connection with God, is eventually able to avoid all external form and is immersed entirely in the bliss of undifferentiated Love in Truth.
Altogether, bhakti resulted in a mass of devotional literature, music and art that has enriched the world and gave India renewed spiritual impetus, one eschewing unnecessary ritual and artificial social boundaries. See bhakti yoga for more.
According to the most famous Western Tantrik scholar, Sir John Woodroffe (pseudonym Arthur Avalon): "The Indian Tantras, which are numerous, constitute the Scripture (Shastra) of the Kaliyuga, and as such are the voluminous source of present and practical orthodox 'Hinduism'. The Tantra Shastra is, in fact, and whatever be its historical origin, a development of the Vaidika Karmakanda, promulgated to meet the needs of that age. Shiva says: 'For the benefit of men of the Kali age, men bereft of energy and dependent for existence on the food they eat, the Kaula doctrine, O auspicious one! is given' (Chap. IX., verse 12). To the Tantra we must therefore look if we would understand aright both ritual, yoga, and sadhana of all kinds, as also the general principles of which these practices are but the objective expression." (Introduction to Sir John Woodroffe's translation of "Mahanirvana Tantra.")
The word "tantra" means "treatise" or "continuum", and is applied to a variety of mystical, occult, medical and scientific works as well as to those which we would now regard as "tantric". Most tantras were written in the late Middle Ages and sprang from Hindu cosmology and Yoga.
Many Hindus are vegetarians (do not eat meat) because of their respect for life. About 30% of today's Hindu population, especially in orthodox communities in South India, in certain northerly states like Gujarat, and in many Brahmin areas around the subcontinent, are vegetarian.
Most Hindus who do eat meat do not eat beef. Some do not even use leather products. This is most likely because many Hindus have relied so heavily on the cow for all sorts of dairy products, tilling of fields and fuel for fertiliser that its status as a willing 'caretaker' of humanity grew to identifying it as an almost motherly figure. Thus, while most Hindus do not worship the cow, and rules against eating beef arose long after the Vedas had been written, it still has an honored place in Hindu society. It is said that Krishna is both Govinda (herder of cows) and Gopala (protector of cows), and Shiva's attendant is Nandi, the bull. With the stress on vegetarianism (which is usually followed even by meat-eating Hindus on religious days or special occasions) and the sacred nature of the cow, it is no wonder that most holy cities and areas in India have a ban on selling meat-products and there is a movement among Hindus to ban cow-slaughter not only in specific regions, but in all of India.
Hindus use many symbols and signs. The two most important symbols used by Hindus are the "Aum" and the "Swastika (Hinduism)".
Contrary to popular belief, practiced Hinduism is neither polytheistic nor strictly monotheistic. The various Hindu gods and avatars that are worshipped by Hindus are understood as different forms of One truth, sometimes seen as beyond a mere god and as a formless Divine Ground (Brahman), akin but not limited to monism, or as one monotheistic principle like Vishnu or Shiva.
