The meaning of this is, that whomsoever we love, in him we find our own soul in the highest sense. The final truth of our existence lies in this. God, the Supreme Soul, is in me, as well as in my son, and my joy in my son is the realisation of this truth.
Whenever our life is stirred by truth, it expresses energy and comes to be filled, as it were, with a creative ardor. This consciousness of the creative urge is evidence of the force of truth on our mind.
