CC Madhya 6.206
bṛhaspati taiche śloka nā pāre karite
Sārvabhauma Bhaṭṭācārya composed one hundred verses in a very short time. Indeed, not even Bṛhaspati, the priest of the heavenly planets, could compose verses as quickly.
The name of the book of one hundred beautiful verses composed by Sārvabhauma Bhaṭṭācārya is Suśloka-śataka.
