I have many times thought while reading the said verse from A.C. Bhaktivedanta Swami's 'Bhagavad Gita as it is' that it could be describing Gandhi or many of todays leaders. I wondered whether others thought so too.
But, strangely enough, from my perspective, it was Gandhi who inspired me to read and understand the Bhagavad-gita many years ago. Gandhi in his autobiography refers to the Bhagavad-gita as the dictionary of life. In India one often hears verses from the Bhagavad-Gita quoted. But it was this statement that actually inspired me to read the Bhagavad-gita.
While Gandhi may fall short of Gaudiya Vaisnava standards, there still are a few things I learnt from him.
The efficacy of Hari nama. Gandhi was a believer in RAma nama.
The concept of a Sadguru.
Practical example of karma yoga. His description of Raychandbhai, who he believed to be so, in his autobiography.
And, finally it was Gandhi who popularised the Vaishnava saint Narsinh Mehta's " Vaishnava Jana to ...."
Perhaps he was unfortunate in never finding the Sadguru he refers to. Gandhi may not have been the perfect saint, which he never claimed, but to the masses, he was still a mahatma.
