Translation:
As Markandeya beheld the child, all his weariness vanished. Indeed, so great was his pleasure that the lotus of his heart, along with his lotus eyes, fully blossomed and the hairs on his body stood on end. Confused as to the identity of the wonderful infant, the sage approached Him.
Purport:
Markandeya wanted to ask the child about His identity and therefore approached Him.
