Based on Bhagavad Gita Chapter 07, Text 19
Some people think that the path of bhakti is too simplistic and so is meant for sentimental non-intellectual people.
However, the simplicity characteristic of bhakti is not simple-mindednessbut simple-heartedness. Let’s understand the difference between the two:
Simple-mindedness: In much contemporary intellectual discourse, the mind refers to the intellectual faculty, as when a thinker is honored as “one of the greatest minds of the century.” In this parlance, simple-mindedness refers to intellectual naiveté, the inability to reason critically and coherently. Only the most historically ignorant people can claim that bhakti is for the simple-minded. The leading exponents of bhakti like Ramanuja, Vyasatirtha and Jiva Goswami rank among the best minds that the world has ever seen, as even a cursory perusal of their intellectual works will reveal. That even the simple-minded can practice bhakti is evidence of its inclusiveness, not its non-intellectualness.
