Once you have changed yourself and you have gone above that, then you can tell somebody as a help. Then it will not be personal. It will not be out of the pride or the ego but it will be out of love because you want that person, also, to reach that level. If somebody is doing something not good, you will tell them: 'Look, you can do it like this or like that.' Then it will not be out of the pride or the ego."
Use the gifts of the Guru wisely. Remember illusion is of the mind and the wisdom of Love and Devotion, True Bhakti, goes beyond the illusion of the mind and resides in the heart of man as Divine Love.
