Nandin said: The ashes should be perfectly cleaned by means of Praṇava. It must be taken from what remains after performing Agnihotra. When the sun has risen in the morning the Agnihotra should be performed with the Mantra “jyotiḥ sūryaḥ.”[10] In the evening the same should be performed with the Mantra “jyotir agniḥ”.[11] If the sun has not risen fully, the performance of Agnihotra is rendered ineffective. The ashes of the sacrifice performed alter the sun has risen is alone sacred and splendid.
