There was a scholarly priest, who was delivering a sermon on a philosophical scripture called Astavakra Samhita. In that scripture, there was a certain verse which can be translated as follows: "The mother and the son of this birth are born as wife and husband of each other in the next birth, owing to the attachment of the mother to the body of her son." The scholar simply could not accept this outrageous statement due to the social stigma associated with this idea.
This particular scholar was a true seeker of the truth. Neglecting what he could not understand or accept or just blindly accepting it, was not an option for him. He had to know the true meaning of the scripture. He had to know the truth even if it was hard to accept. It was in this state when someone told him about Swami, telling him that Swami was an incarnation of the Lord Dattatreya. If there was anyone who could solve his problem, it was Swami.
Swami explained to him the meaning of the verse as follows "In a movie, two actors acted as mother and son. In another movie, the same two actors acted as wife and husband. In reality, the two actors are totally unrelated; they are neither mother-son, nor are they wife-husband. Before the movie the two actors were unrelated, after the movie they are unrelated, only during the movie they temporarily pretend to be related. That which does not exist before and after the shooting of the movie, does not exist even during the time of shooting. The mother-son and wife-husband relationships are totally unreal. In each of the movies they are only co-actors or co-employees of the same movie producer. However the employer-employee relationship between the movie producer and actors remains before the movie, during the movie and after the movie. It is the only real relationship since it is a relationship whose scope is beyond the unreal movie."
Swami continued to explain, "Relationships between souls in this world are unreal, because these relationships did not exist in the previous birth and will not exist in future births. Therefore, they are both temporary and unreal. The only permanent relation that a soul has is that with God, the Producer of this Cosmic Cinema. This relation is permanent and real. It was there in the past, it is there in the present and will remain in the future. When a person dies here on earth, his soul with its subtle body (past impressions and feelings) leaves the gross body. The gross physical body is left here and it disintegrates. As soon as the soul leaves the body, all relationships in this world are also left behind. The soul retains no memory of who his parents, spouse or children were in the past birth. However, the bond with God remains. Our attachment to worldly relationships is foolish. When Abhimanyu, the valiant son of Arjuna, died in the Mahabharata war, Arjuna was overcome with grief. He decided to stop the war. Lord Krsna tried His best to convince Arjuna to stop grieving unnecessarily but it was all in vain. Finally, in order to show the impermanence of all worldly relationships, He took Arjuna to heaven. There Arjuna saw Abhimanyu enjoying the pleasures of heaven. Arjuna ran to Abhimanyu and embraced him. Abhimanyu was surprised and asked Arjuna "Who are you?" Arjuna told him that he was Abhimanyu's father. Abhimanyu replied that he had had millions of births and in exactly which birth was Arjuna his father? Clearly Abhimanyu remembered nothing about his past birth and relationships. Arjuna saw the futility of attachments in this world. He had seen the proof that all worldly bonds are unreal".
When the scholar heard this explanation, he fell at the feet of Swami crying. He had finally understood the true meaning of that scriptural verse. He praised Swami, "You are undoubtedly Lord Datta. No one can explain the scriptures as You have, O Guru Datta!"
