Even today, poets when describing the gait of a woman, compare it to that of a ‘hamsa’ (swan). It has been centuries since the swan has become extinct from this world. It is not possible for poets of today’s world to have actually seen its beauty. The reference to its elegant movements is a mere replication of the thoughts of yesteryear poets who have actually seen it.
Likewise, when we describe the enchanting beauty of Bhagavan Sri Krishna, it is only a replication of the reference done in our scriptures and the Divine Works of Mahatmas who have directly seen Bhagavan in His Blissful Form. Bhagavan’s Majestic Form, His Endearing Smile, His Lotus Feet, have to be truly experienced by having His Divine Darshan, to be able to expound it. Else, it will remain a mere replication.
