Parable about the Single Seed of Truth

This parable is about a young man Amrit (‘immortal’) who was a disciple of the greatest woman-sage — Mistress Vidya (‘Knowledge’). When Amrit had grown up and could control his thoughts, emotions and subdue his anger, She sent him to see the world that he could find and know the Single Seed of Truth.  Whom did Amrit meet on his way? What happened to him? What did he find and know during his journey? What is the #SingleSeedofTruth? Did he know it?  All answers on this question will reveal a difference of two knowledges — knowledge of mind and knowledge of the Soul.
