घुणाक्षर न्याय (Gunākshara Nyāya) – The maxim of the letters made by the wood worm, Ghuna.
This worm bores holes in wood and in books which sometimes assume the shape of a letter; hence it is used to denote the occurrence of something quite accidental, or a chance occurrence. Chakrapani in Deerghamjeeviteeyam Adhyaya refers this Nyaya while explaining the Samyagyukta Bheshaja Lakshana. Bheshaja when properly used gives Arogya.
A physician who is Jnaanavan can only do the proper Yojana of the Bheshaja. One who attains good results without proper Jnāna is by Yadrucchaa, that is, by chance. It is like Ghunaakshara – the worm accidentally causing an Akshara. This highlights the requirement of Jnāna for Samyagyojana of Bheshaja and the Siddhi of Chikitsaa.
Do you have any instance in life where things happened accidentally, by chance, and not by design or by the application of your Jnāna?
