• Vallabhacharya was the founder of Pushtimarga (way of grace). Sur Das preached religion of love and devotion to a personal God. 

• He wrote inspiring and moving poems, Hindi poems about Lord Krishna. Krishna’s bal lila constitutes the first great theme of Sur Das poetry.  
• According to him, love is a sublimated theme representing the irresistible attraction of the gopis of Brindavan towards Krishna.  
• The intensity of passion displayed by the gopis is an expression of the natural attraction of the human spirit towards the divine soul.
