Has age any relevance in the spiritual realm ?
It is not age that matters. A person may be old, but his heart may be fresh and tender, full of enthusiasm for service and willingness to sacrifice. That will ensure your getting the passport to the spiritual realm. Divinity is only the terminus of the journey of human life, like the ripe fruit being the terminus of the journey from bud through blossom, from blossom to the fruiting, the sour bitter fruit to the sweet juicy ripeness. Grace is the sunlight, which will ripen the fruit. Sadhana is the sap, which rises from the earth. Both are needed by the tree, in order that it may yield fruit.
