The mature stage of bhakti is bhava. When one attains it one remains speechless, thinking of Satchidananda.
The feeling of an ordinary man can go only that far.
When bhava ripens it becomes mahabhava.
Prema is the last.
You know the difference between a green mango and a ripe one.
Unalloyed love of God is the essential thing.
All else is unreal.
