Varadaraja wrote the Laghusiddhantakaumudi, a short version of Bhattojidiksita's Siddhantakaumudi, in order to inculcate an ability in beginners to gain access to the Astadhyayi as he claims in the invocatory verse This work, which is the first of the three-volume project, covers 371 sutras on samjna, sandhi, subanta and avyaya prakaranas.
It includes the translation of the sutra and the vrtti on it by Varadaraja, which is followed by the paraphrased sutra in which padas are kept in nonsandhi form. The carried over padas are given along with the sutras from the Astadhyayi from which they have been carried over.
In the clucidation that follows the paraphrase, the meaning of the sutra and the vrtti thereon is explained in detail. Relevant grammatical aspects have also been discussed so that some light is thrown on the depth and nuances of vyakarana-sastra. The present work fulfils a compelling need for a detailed commentary on the laghusiddhantakaumudi in English.
