1.23.456

oṃ namo 'mṛte amṛtarūpiṇi amṛtaṃ kuru kuru evaṃ rudra ājñāpayati svāhā /
saptābhimantritaṃ kṛtvā mantreṇānena tajjalam /
dinamekaṃ tathā sūtaṃ svarṇamāṣadvayānvitam //

'Om, salutations to Amṛtā, whose form is nectar! Make nectar, make nectar! Thus Rudra commands: svāhā!'
Having consecrated that water seven times with this mantra,
and quicksilver along with two māṣas of gold for one day,
