Andhaka to look after Lohitang

Lord Shiva forbids Indradev from taking care of Lohitang. He asks Andhaka to look after Lohitang's nourishment. Lord Shiva blesses Natyacharya for learning tandava from him. He makes the rishis realise their misdeed against Narayan. Will the rishis be able to atone for this?
