Scriptures

The ancient scriptures of Hinduism are in Sanskrit. These texts are classified into two: Shruti and Smriti. Shruti is apauruṣeyā, "not made of a man" but revealed to the rishis (seers), and regarded as having the highest authority, while the smriti are manmade and have secondary authority. They are the two highest sources of dharma, the other two being Śiṣṭa Āchāra/Sadāchara (conduct of noble people) and finally Ātma tuṣṭi ("what is pleasing to oneself").

Hindu scriptures were composed, memorised and transmitted verbally, across generations, for many centuries before they were written down. Over many centuries, sages refined the teachings and expanded the Shruti and Smriti, as well as developed Shastras with epistemological and metaphysical theories of six classical schools of Hinduism.

Shruti (lit. that which is heard) primarily refers to the Vedas, which form the earliest record of the Hindu scriptures, and are regarded as eternal truths revealed to the ancient sages (rishis). There are four Vedas – Rigveda, Samaveda, Yajurveda and Atharvaveda. Each Veda has been subclassified into four major text types – the Samhitas (mantras and benedictions), the Aranyakas (text on rituals, ceremonies, sacrifices and symbolic-sacrifices), the Brahmanas (commentaries on rituals, ceremonies and sacrifices), and the Upanishads (text discussing meditation, philosophy and spiritual knowledge). The first two parts of the Vedas were subsequently called the Karmakāṇḍa (ritualistic portion), while the last two form the Jñānakāṇḍa (knowledge portion, discussing spiritual insight and philosophical teachings).

The Upanishads are the foundation of Hindu philosophical thought, and have profoundly influenced diverse traditions. Of the Shrutis (Vedic corpus), the Upanishads alone are widely influential among Hindus, considered scriptures par excellence of Hinduism, and their central ideas have continued to influence its thoughts and traditions. Sarvepalli Radhakrishnan states that the Upanishads have played a dominating role ever since their appearance. There are 108 Muktikā Upanishads in Hinduism, of which between 10 and 13 are variously counted by scholars as Principal Upanishads.

The most notable of the Smritis ("remembered") are the Hindu epics and the Puranas. The epics consist of the Mahabharata and the Ramayana. The Bhagavad Gita is an integral part of the Mahabharata and one of the most popular sacred texts of Hinduism. It is sometimes called Gitopanishad, then placed in the Shruti ("heard") category, being Upanishadic in content. The Puranas, which started to be composed from c. 300 CE onward, contain extensive mythologies, and are central in the distribution of common themes of Hinduism through vivid narratives. The Yoga Sutras is a classical text for the Hindu Yoga tradition, which gained a renewed popularity in the 20th century.

Since the 19th-century Indian modernists have re-asserted the 'Aryan origins' of Hinduism, "purifying" Hinduism from its Tantric elements and elevating the Vedic elements. Hindu modernists like Vivekananda see the Vedas as the laws of the spiritual world, which would still exist even if they were not revealed to the sages.

Tantra are the religious scriptures which give prominence to the female energy of the deity that in her personified form has both gentle and fierce form. In Tantric tradition, Radha, Parvati, Durga and Kali are worshipped symbolically as well as in their personified forms. The Agamas in Tantra refer to authoritative scriptures or the teachings of Shiva to Shakti, while Nigamas refers to the Vedas and the teachings of Shakti to Shiva. In Agamic schools of Hinduism, the Vedic literature and the Agamas are equally authoritative.
