Shruti (lit: that which is heard) primarily refers to the Vedas, which form the earliest record of the Hindu scriptures. While many Hindus revere the Vedas as eternal truths revealed to ancient sages (Ṛṣis), some devotees do not associate the creation of the Vedas with a god or person. They are thought of as the laws of the spiritual world, which would still exist even if they were not revealed to the sages.Hindus believe that because the spiritual truths of the Vedas are eternal, they continue to be expressed in new ways.
There are four Vedas (called Ṛg-, Sāma-, Yajus- and Atharva-). The Rigveda is the first and most important Veda. Each Veda is divided into four parts: the primary one, the Veda proper, being the Saṃhitā, which contains sacred mantras. The other three parts form a three-tier ensemble of commentaries, usually in prose and are believed to be slightly later in age than the Saṃhitā. These are: the Brāhmaṇas, Āraṇyakas, and the Upanishads. The first two parts were subsequently called the Karmakāṇḍa (ritualistic portion), while the last two form the Jñānakāṇḍa (knowledge portion). While the Vedas focus on rituals, the Upanishads focus on spiritual insight and philosophical teachings, and discuss Brahman and reincarnation.
A well known shloka from Brihadaranyaka Upanishad is:
ॐ असतो मा सद्गमय । तमसो मा ज्योतिर्गमय ।।IAST:
मृत्योर्मामृतं गमय । ॐ शान्ति शान्ति शान्ति ।।
– बृहदारण्यक उपनिषद् 1.3.28.
om asato mā sadgamaya | tamaso mā jyotirgamaya ||Translation:
mṛtyor mā amṛtaṁ gamaya | om śānti śānti śānti ||
– bṛhadāraṇyaka upaniṣada 1.3.28
Lead Us From the Unreal To the Real |Smritis:
Lead Us From Darkness To Light ||
Lead Us From Death To Immortality |
OM Let There Be Peace Peace Peace.||
– Brihadaranyaka Upanishad 1.3.28.
Hindu texts other than the Shrutis are collectively called the Smritis (memory). The most notable of the smritis are the epics, which consist of the Mahābhārata and the Rāmāyaṇa.
The Bhagavad Gītā is an integral part of the Mahabharata and one of the most popular sacred texts of Hinduism. It contains philosophical teachings from Krishna, an incarnation of Vishnu, told to the prince Arjuna on the eve of a great war.
The Bhagavad Gītā, spoken by Krishna, is described as the essence of the Vedas.However Gita, sometimes called Gitopanishad, is more often placed in the Shruti, category, being Upanishadic in content. Purāṇas, which illustrate Hindu ideas through vivid narratives come under smritis. Other texts include Devī Mahātmya, the Tantras, the Yoga Sutras, Tirumantiram, Shiva Sutras and the Hindu Āgamas. A more controversial text, the Manusmriti, is a prescriptive lawbook which lays the societal codes of social stratification which later evolved into the Indian caste system.
A well known verse from Bhagavad Gita describing a concept in Karma Yoga is explained as follows
To action alone hast thou a right and never at all to its fruits;
- let not the fruits of action be thy motive;
- neither let there be in thee any attachment to inaction.
