Question

Hello Rabbi,
I heard that Rabbi Ovadia placed a bouquet of red lilies on the grave of the Ben Ish Chai, and at the end of the prayer there the lilies turned white. They explained that this was because the Ben Ish Chai represents the attribute of judgment and is stringent according to Kabbalah, whereas Rabbi Ovadia represents the attribute of kindness and is lenient according to the plain meaning. Is this story true?
