A similar quotation is found in My Heart Shall Give A Oneness-Feast (1993) by Sri Chinmoy: "My books, they all have only one message: the heart's Power Of Love must replace the mind's Love Of Power. If I have the Power Of Love, then I shall claim the whole World as my own … World Peace can be achieved when the Power Of Love replaces the Love Of Power." An even earlier statement of Chinmoy is found in Meditations: Food For The Soul (1970): "When the power of love replaces the love of power, man will have a new name: God."

Variant: We must discover the power of love, the power, the redemptive power of love. And when we discover that we will be able to make of this old world a new world. We will be able to make men better. Love is the only way.
Context: But there is another way. And that is to organize mass non-violent resistance based on the principle of love. It seems to me that this is the only way as our eyes look to the future. As we look out across the years and across the generations, let us develop and move right here. We must discover the power of love, the power, the redemptive power of love. And when we discover that we will be able to make of this old world a new world. We will be able to make men better. Love is the only way.

This quote has been attributed to Hendrix on the internet, and is flatly denied to have ever been said by him, without presenting any evidence as to why, beyond such unsupported, derisive and denigrative statements such as the author rants about others making in "WHAT HENDRIX NEVER SAID : They Don't Want to Know What He Really Said and Demand a Slacker Fantasy Instead" (22 March 2010) by Michael Fairchild, at rockprophecy.com http://www.rockprophecy.com/hendrix_quotes_hoax.html. Whether or not he ever spoke them, they are very similar to those reportedly of British Prime Minister William Ewart Gladstone, quoted in The Forbes Book of Business Quotations (1997) edited by Edward C. Goodman and Ted Goodman, p. 639: "We look forward to the time when the Power of Love will replace the Love of Power. Then will our world know the blessings of peace." A similar quotation he provides of Sri Chinmoy predates any currently located source of either the Hendrix or Gladstone attributions, yet he accuses Chinmoy of simple plagiarism of Gladstone (or "Gladwell" at one point). From Chinmoy's book My Heart Shall Give A Oneness-Feast (1993) he quotes: "My books, they all have only one message: the heart's Power Of Love must replace the mind's Love Of Power. If I have the Power Of Love, then I shall claim the whole World as my own … World Peace can be achieved when the Power Of Love replaces the Love Of Power." An even earlier statement of Chinmoy is found in Meditations: Food For The Soul (1970): "When the power of love replaces the love of power, man will have a new name: God."
