Sūtra (Sanskrit: सूत्र, Pāli: sutta, Ardhamagadhi: sūya) is an aphorism (or line, rule, formula) or a collection of such aphorisms in the form of a manual, or, more broadly, a text in Hinduism or Buddhism. Literally it means a thread or line that holds things together and is derived from the verbal root siv-, meaning to sew (these words, including Latin suere and English to sew, all ultimately deriving from PIE *siH-/syuH- 'to sew'), as does the medical term "suture."

In Hinduism sutra denotes a distinct type of literary composition, based on short aphoristic statements, generally using various technical terms. This literary form was designed for concision, as the texts were intended to be memorized by students in some of the formal methods of scriptural and scientific study (Sanskrit: svādhyāya). Since each line is highly condensed, another literary form arose in which commentaries (Sanskrit: bhāṣya) on the sutras were added, to clarify and explain them.

In Brahmin lineage, each family is supposed to have one Gotra, and one Sutra, meaning that a certain Veda (Śruti) is treasured by this family in way of learning by heart.

Ravi Shankar (Bengali: রবি শংকর; born Robindro Shaunkor Chowdhury on 7 April 1920), often referred to with the title Pandit, is an Indian musician and composer who plays the plucked string instrument sitar. He has been described as the most known contemporary Indian musician by Hans Neuhoff in Musik in Geschichte und Gegenwart.

Shankar was born in Varanasi and spent his youth touring Europe and India with the dance group of his brother Uday Shankar. He gave up dancing in 1938 to study sitar playing under court musician Allauddin Khan. After finishing his studies in 1944, Shankar worked as a composer, creating the music for the Apu Trilogy by Satyajit Ray, and was music director of All India Radio, New Delhi, from 1949 to 1956.

In 1956, he began to tour Europe and America playing Indian classical music and increased its popularity there in the 1960s through teaching, performance, and his association with violinist Yehudi Menuhin and George Harrison of The Beatles. Shankar engaged Western music by writing concerti for sitar and orchestra and toured the world in the 1970s and 1980s. From 1986 to 1992 he served as a nominated member of the upper chamber of the Parliament of India. Shankar was awarded India's highest civilian honor, the Bharat Ratna, in 1999, and received three Grammy Awards. He continues to perform in the 2000s, often with his daughter Anoushka.
