Sutram sutravido viduh
A Sutra or an aphorism is a short formula with the least possible number of letters, without any ambiguity or doubtful assertion, containing the very essence, embracing all meanings, without any stop or obstruction and absolutely faultless in nature.
The Sutrakara or the composer of the aphorisms is said to be as happy as one would be while getting the first male child, if he is but able to reduce one letter in his abstruse Sutra of far-fetched words and ideas.
The best example of the greatest, the tersest and the most perfect of Sutra literature is the series of aphorisms called the Ashtadhyayi composed by Panini.
Panini is the father of all Sutrakaras from whom all others seem to have borrowed the method of composition. The Sutras are meant to explain a big volume of knowledge in short assertions suitable to be kept in memory at all times.
The six Vedangas and the six systems of Hindu philosophy form the twelve sets of Sutra literature of the world. In addition to these, there are later compositions like the Narada-Bhakti Sutras, the Sandilya-Bhakti Sutras, etc., which also wish to assume an equal form with the famous Sutras mentioned above.
