Views

Thoughts on caste
Caste is a crippling disease. The physician’s duty is to guard against disease or destroy it. Caste organization crushes the individual under its dead weight and hinders progress by killing all consciousness of liberty.

Thoughts on women 
Though perfectly consistent with the principles of the Dhamma, which sees no difference between man and man, except that which may exist by superiority of virtue, yet the step taken by the Buddha and his followers was indeed bold, considering the depraved moral condition of Ancient India and the consequent low self-estimation in which woman was then held. 
Thoughts on Science: The scientific method is at once experimental and rational, requiring such evidence as will make doubt impossible. Science aims at obtaining a complete systematic survey of all possible phenomena in terms of irreducible elementary processes. Knowledge that is not scientific is not to establish immutable truths and eternal dogmas, but to approach truth by approximations.

Death 
Prof. P. L. Narasu passed away at the age of seventy-three on 14 July 1934, due to heart problems. His body was cremated in a simple Buddhist ceremony in the Mylapore burning-yard.

Writing 
Narasu wrote many books especially in English. His books have been translated into many languages.
