Letters of Sri Aurobindo
Volume III - Part 4
It [the flow of love and joy from the heart centre] can be misused on a large scale only if there is a strong and vehement vital ego not accustomed to correction or else a vital full of the kāmavāsanā. On a small scale it can be misused by the small 
selfishnesses, vanities, ambitions, demands of the lower vital supporting themselves upon it. If you are on guard against these things then there is no danger of misuse. If the psychic puts forth psychic discernment along with the love, then there is no danger, for the light of psychic discernment at once refuses all mixture or misuse.
