xxiv. 7. Then the basis of the Bṛhat (is recited). 'They call thee, men, when (the juice) is pressed' is a couplet, to avoid isolation; (it is used, thinking) 'Let not that Bṛhatī have been recited by itself alone as it were.'

'The singers sing thee' is the Niṣkevalya in Anuṣṭubhs, containing (the word) 'up' in 'Up with a rod they have raised thee', and connected with the Bṛhat. 'These thee, O thou of much light' is the Pragātha, containing (the word) 'who (*ka*)' in *kavarṇa* in 'of pure hues (*pāvakavarṇāḥ*)'; the explanation of this has been given.
