Not out of a mere surface sentiment of love and sympathy

To live an inner life does not mean imprisonment within the four walls of one’s personal self; on the contrary, it is the first step towards a true universality. It brings to us the truth of ourselves as well as the truth of other selves, for this inner living can penetrate the life of all much more thoroughly than any surface consciousness can do. It is for this reason that in the gnostic or divine being, in the gnostic or divine life, there is a complete and intimate knowledge of the self of others, a complete and intimate knowledge of their mind, life, physical being. This enables the gnostic being to act not out of a mere surface sentiment of love and sympathy, but out of this full and intimate knowledge of other selves…

Well, the solution is that given in the last chapter of The Life Divine. Live your true inner life, for that is the first step towards the divine life. That will be the best way to create a life of unity, mutuality and harmony. -- An introduction to the philosophy of Sri Aurobindo by S.K.
