इक्षुरस means sugarcane juice. This Nyaya is conceptualised keeping in mind sugarcane and sweet juice that is obtained from it.
Nature has bestowed a gift upon stall of sugarcane with sweet juice. So sweet juice in every stalk of sugarcane is very natural. But if we want to get benefit of it i.e. sweet juice we have to first extract it. For this we have to crush sugarcane in a sugarcane crushing machine. If a person does not crush sugarcane remaining more sensitive or his generous nature sugarcane will with the passing of time get dried up. In such a situation inspite of there being sweet juice in sugarcane it cannot come out consequently, its advantage cannot be reaped. Sweet juice bestowed by nature will serve no purpose.
This 'Nyaya' preaches / advises that even if a man has many talents, but if attempts are not made to draw them out, they serve no purpose.
Every student has some or other talent/capabilities. Attempts are necessary to draw them out. For this as sugarcane needs to be crushed, the student also needs. to be crushed in the crushing machine of experience appropriate to his worth. If that is not done the capability, the talent of the student does not develop, it remains dormant in him or her and the society at large and he or she himself or herself cannot get any advantage of it.
