It is crystal clear that all work for all souls is done by God. Soul just keeps on moving from life to life in search of the permanent happiness. In the process he tries all the relation with other souls which themselves are in the search of the permanent happiness. Which means a beggar begging to a beggar. The result is both remain beggars.

That is what exactly happening with all. No one is happy permanently because relations are established with the persons who don't have access to infinite happiness.

So, let us check the answer to the second question....who is mine? If you had gone through the previous discussion on this matter, the answer is self-coming.

As God does everything for soul and soul does not do anything for other soul rather soul does everything to seek self-happiness and all its relationship with other souls are based on the premise that its self-happiness would be found. It implies that there cannot be any real relationship between soul to soul.

Then the answer is God is mine. Krishn is mine. And with what relationship? All.He gives body - the birth - He is Mother.He provides every thing to soul - He is Father.He preaches - He is Teacher.He gives advice - He is friend.He strives for soul's happiness and hence he has all other relation with soul:He is brother. He is sister. He is well wisher. He is husband. He is beloved. In fact he is only and one in all relative of soul.
