Our last darling is our body.
No matter how much time and effort
we lavish in making it look good,
it will leave us when we die.

Our next darling is our possessions,
status and wealth.
When we die,
it will all go to others.

Then our next darling is our family and friends.
No matter how much they have been there for us,
the furthest they can stay by us is up to the grave.

Hence, Our 1st darling is nothing but, our Soul which will follow us all the time, where ever we go. 
But is often neglected in pursuit of wealth,
power and pleasures of the world.

We the Soul / Aatma only and alone can go and reach the Supreme Soul / Paramatma.
