While spirituality has to do with Self realization and knowing the creator, spirituality also has to do with seeing GOD in its creation. An analysis leads man to the TRUE knowledge where the creation has to be separated from Creator to understand almighty.
This analysis (division of TRUTH and the false WORLD) subsequently has to end into synthesis where creator and creation blend into ONE.
It is this union that brings SAGUN into NIRGUN. Such a blend is lived by a saint who lives with GOD as he interacts with Community and the Universe.
Unless, our actions get dedicated to service of creation, the mission remains unaccomplished. Know GOD and then Serve GOD through service unto HIS creation.
