Unconditional love - Is this possible for any human except for Sri rama and krishna? Our friend Penpillai knows about a person. Thiruppanazhwar was not allowed to enter the temple premises due to the caste system prevalent in those times. Despite not having seen the Lord, he continued to show his love by singing perumal's kalyana gunas. One day, the Lord decided to show his beautiful divine form to Thiruppanazhwar.
