The fig tree is a person whose life makes a full show of leaves and yet bears no inner fruit, all outward religion and no awakened awareness within. The higher self, hungry for real substance, comes and finds only the display, the covering foliage of belief and observance with nothing ripened underneath. When such a state is seen for what it is, it withers; a way of being that only performs and never bears cannot last, and it dries from the root once the light of awareness falls on its emptiness.
Leaves without fruit is a life crowded with religious appearance but empty of any real inner change. What happens is that such barren display, once seen clearly, simply dries up and falls away.
Fig tree: a person's whole religious life, leafed out in appearance yet meant to bear real inner fruit
Leaves: the outward show of belief and observance, the covering that hides an emptiness beneath
