ful, no doubt, for the study of grammar, but no topic belonging to Siksa is given by Panini which apparently means that these works do not come under the subject or province of Grammar. The reason why the Siksa topics are not given by Panini, is worth consideration. These Siksa works are not speci- fically related to a particular Veda and it cannot be said whether they preceded or succeeded the Pratisakhya works.

शिखा one of the subdivisions of the artificial recitals of the Vedic texts.

P.III.4.113), while, the Adesas or substitutes, marked with the indicatory श्, are substituted for the whole of the Sthanin or the original and not for its final letter according to the rule अलोन्त्यस्य P.

The Sivasutras have got a well-known explanation in Verse, named नन्दिकेश्वरकारिका on which there is a commentary of the type of Bhasya by उपमन्यु.
