Among methods of learning Sanskrit, there seem to be different schools of thought. Recently I got two books, Parts 1 and 2 of संस्कृत पठन-पाठन की अनुभूत सरलतम विधि by पं. ब्रह्मदत्त जिज्ञासु, published by रामलाल कपूर ट्रस्ट, रेवली, सोनीपत – ३९, हरियाणा. On the cover page itself there is a declaration बिना रटे ६ मासमें अष्टाध्यायी-पद्धतिसे संस्कृत का पठन-पाठन, meaning Learning and Teaching Sanskrit in 6 months by अष्टाध्यायी-method, without any rote. अष्टाध्यायी-method means method of learning based on सूत्र-s in अष्टाध्यायी.

Sanskrit-Grammarians seem to agree on a concept that सूत्र-s in अष्टाध्यायी are of six types – (1) संज्ञासूत्राणि – Terminologies (2) परिभाषासूत्राणि – Meta-Rules (3) अधिकारसूत्राणि – by which topics are declared (4) विधिसूत्राणि – Processes (5) अतिदेशसूत्राणि – Extended logic (6) विशेषसूत्राणि – Special or exceptional instances.

Of these six types, my thoughts on परिभाषाप्रकरणम् have been already compiled.

Another important type is अधिकारसूत्राणि – by which topics are declared. In Part 1-book by पं. ब्रह्मदत्त जिज्ञासु he advocates study of following अधिकारसूत्र-s as essential study.

Before that, it is to be borne in mind that every अधिकारसूत्रम् has a range of its अधिकार i.e. command-range. I calculated these from अष्टाध्यायी-सूत्रपाठः as available in a book अष्टाध्यायी by श्रीगोपालशास्त्री published by चौखम्बा सुरभारती प्रकाशन, वाराणसी.

It is to be borne in mind however that wherever the range includes the सूत्रम् (3-3-1) उणादयो बहुलम् the count of number of सूत्र-s does not include सूत्र-s in उणादि-subset, implicit in this सूत्रम्.

I am excited that I have put the अधिकारसूत्राणि mentioned by पं. ब्रह्मदत्त जिज्ञासु and their command-ranges as calculated in a single diagram. I wonder whether anybody has ever presented a pictorial view of अष्टाध्यायी with the specific context of अधिकारसूत्राणि. Here it is –

शुभमस्तु !
