Sanskrit prosody

Sanskrit prosody, also known as Chandas, is the study of poetic metres and verse in the ancient Sanskrit language. It is one of the six Vedangas, or limbs of Vedic studies, which were essential parts of understanding and preserving the Vedas, the sacred texts of Hinduism. Because the Vedas were often composed in carefully measured verse, the rules of Sanskrit prosody were very important to scholars and poets.

The Vedic schools organized their metres around seven major types, each with its own rhythm and style. Some metres were based on a fixed number of syllables in each verse, while others used a counting system called morae. This created a rich tradition of poetry and chanting that influenced many later texts.

Important ancient manuals on Sanskrit prosody include Pingala’s Chandah Sutra. Later works, such as Kedara Bhatta's Vrittaratnakara, also helped preserve these traditions. In total, Sanskrit prosody includes descriptions of over 600 different metres — more than any other metrical tradition in the world.

Etymology

The word Chandas (Sanskrit: छन्दः/छन्दस् chandaḥ/chandas) means something that is pleasing, lovely, or delightful. It comes from a root word that means to feel good or to nourish. In Sanskrit literature, Chandas also refers to the metrical parts found in the Vedas and other poetic works.

History

The study of Chandas, or Sanskrit prosody, began thousands of years ago with the hymns of the Rigveda. These hymns mention different metres, showing that the rules of poetry were already important. Later texts, like the Brahmanas, explained these rules clearly.

Many ancient scholars wrote about Chandas. The oldest surviving book on this topic is the Chandahsutra by Pingala, written between 600 and 200 BCE. Over time, many other scholars added their own comments and ideas to help people understand these rules better. Important Hindu books, such as the Agni Purana and Natya Shastra, also included sections about Chandas.

Elements

The metres in classical Sanskrit poetry are sorted into three types based on how they are measured.

1. Syllabic verse depends simply on counting the number of syllables in each line, allowing flexibility in which syllables are short or long. This style comes from older Vedic forms and appears in famous poems like the Mahabharata and the Ramayana.
2. Syllabo-quantitative verse also counts syllables, but the pattern of short and long syllables is fixed.
3. Quantitative verse measures the duration of each line, counting units called morae. Each line has a set number of these units, usually grouped into sets of four.

Most Sanskrit poems are made up of lines divided into four parts, called pādas ("feet"). The rhythm comes from the pattern of laghu (short) and guru (long) syllables within each pāda. The rules for deciding which syllables are short or long are the same as those used in normal Sanskrit writing, explained in special sound-study texts called Shiksha.

A short syllable has a short vowel sound and is followed by one consonant at most before the next vowel. A long syllable either has a long vowel sound or is a short vowel followed by a group of consonants. Special sounds like 'ṃ' (anusvara) and 'ḥ' (visarga) are always long.

The seven birds: major Sanskrit metres

Sanskrit prosody, also known as Chandas, studied special ways to write poems and verses. It had seven main metres, called the "seven birds" or "seven mouths of Brihaspati". Each metre had its own rhythm and style.

These seven metres include the Gāyatrī, Anustubh, Tristubh, Jagati, Ushnih, Brihati, and Pankti. They were used to create beautiful poems and hymns in ancient times.

Metres as tools for literary architecture

The Vedic texts and later Sanskrit literature were written in specific rhythms, called metres, to help people remember and understand them. Each section or chapter used the same metre, making it easier for readers to know when one part ended and another began. Authors often signaled the end of a hymn by using a different metre in the last verse, except for the Gayatri metre, which was considered too sacred to use in this way.

Scholars have studied these metres to check if texts might have been changed over time. Sometimes, a change in metre can show that parts of a text were added later by different authors. However, not all changes mean the text isn’t authentic, as some poets simply used different styles.

Texts

The Chandah Sutra is an ancient Hindu text written by Pingala. It is one of the oldest books about poetry rules and rhythms, dating back to between the 6th and 2nd centuries BCE. The book has 310 short rules, or sutras, in 8 sections. It talks mostly about how to create poetic meters, and it even includes some early math ideas used in music.

Over the years, many people wrote explanations, called Bhashyas, to help others understand the Chandah Sutra. One important example is Chandoratnakara, written in the 11th century by Ratnakarashanti. This work added new ideas about poetry in Prakrit and had influence in Nepal and Tibet. Another commentary came in the 18th century by Bhaskararaya, called Chandahsutrabhasyaraja.

Usage

The Hindu epics and later Sanskrit poetry often use a structure of four-line stanzas called pādas. Each line follows a specific rhythm, and sometimes pairs of lines are read together for beauty. One common metre is the Anushtubh, which has eight syllables per line and was widely used in later Sanskrit works.

Ancient Indian scholars studied patterns in these metres, leading to early ideas in mathematics. They developed methods to count and arrange these rhythms, creating sequences similar to what we now call the Fibonacci numbers. They also created patterns that match the Pascal's triangle known in Western mathematics today.

Influence

The Chandas, or Sanskrit prosody, are an important part of Hindu literary traditions. They are one of the five main categories of literary knowledge, along with expression forms, writing styles, tropology, and aesthetic moods. The Gayatri metre is especially sacred and is still used today in Yoga and hymns.

Sanskrit prosody also influenced poetry in Southeast Asia, such as the Thai Chan. This influence likely reached Thailand through Cambodia or Sri Lanka. Chinese literature from the 6th century also shows signs of Sanskrit prosody, probably introduced by Buddhist monks who traveled to India.
