"Sai' has his own divine colours, the colours of rainbow, so attractive with the spiritual beauty which has its own significance - Beauty with a cause. 'His' every picture is so attractive that a devotee gets attracted to 'him' the first time.
For lets us observe the photo in which 'Sai' is sitting in the "Dwarka-Mai". Sai is trying to signify that I am totally yours from top to bottom. I am your ever saver in every aspect or is he trying to see the beauty of the world and trying to explain that how beautiful the world has been created and what we need is peace and hence passing the message of performing one's duty with peace
and satisfaction.
He is waiting for his Bhakta's to come near 'him' and discuss with 'him' their problems and decisions. As Baba says
"If you look to me I look to you'.
May Sai Bless us all.
