intellect

Do not lend your intellect [buddhi] 

as a slave 

to the gymnastics of eloquence 

[in the form of speech and poetry] and 

to the jugglery of arguments. 

Know the truth, Self, 

by turning the pure sattvic mind within

and thereby 

destroying the illusion of otherness.

- The teachings of Sri Ramana Maharshi. Guru Vachaka Kovai. Verse 526. The Practice of the Truth. Chapter 6. The Delusion of Arguments
