Śiva-nāmānukīrtana-prastāvaḥ
Prologue to the praise of Śiva and the Upamanyu testimony
तथेति भगवानाह तस्य तद् वचन प्रभु: । स्वायम्भुव: क्रतुश्चापि पुत्रार्थम भवत् पुरा
tatheti bhagavān āha tasya tad vacana-prabhuḥ | svāyambhuvaḥ kratuś cāpi putrārtham abhavat purā ||
婆苏提婆说道：那大能的主听了他的话，答曰：“如是（tathāstu）。”遂允其所求。同样在久远以前，斯瓦扬布之子克罗图为求子嗣，修瑜伽三百年，心念恒系于湿婆；因此，商羯罗也赐予克罗图一千子嗣，如同先前所赐一般。

Educational Q&A
The verse underscores that sustained discipline (yoga/tapas) and focused devotion can bear fruit, and that divine assent (“tathāstu”) is portrayed as responding to sincere, long-term spiritual effort—here directed toward a legitimate life-goal (progeny).
Vāsudeva recounts a precedent: just as a request was granted with the words “so be it,” Kratu, son of Svāyambhū, practiced concentrated yoga for three hundred years meditating on Śiva, and Śaṅkara rewarded him by granting a thousand sons.
