My dear King Parīkṣit, when Kaṁsa saw that Vasudeva, being situated in truthfulness, was completely equipoised in giving him the child, he was very happy. Therefore, with a smiling face, he spoke as follows.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
दृष्ट्वा समत्वं तच्छौरेः सत्ये चैव व्यवस्थितिम् । कंसस्तुष्टमना राजन् प्रहसन्निदमब्रवीत्
dṛṣṭvā samatvaṃ tacchaureḥ satye caiva vyavasthitim | kaṃsastuṣṭamanā rājan prahasannidamabravīt
