pādayoḥ - at the feet; patitam - fallen; bālam - the boy (Prahlāda Mahārāja); pratinandya - encouraging; āśiṣā - with blessings ('My dear child, may you live long and be happy' and so on); asuraḥ - the demon Hiraṇyakaśipu; pariṣvajya - embracing; ciram - for a long time due to affection; dorbhyām - with his two arms; paramām - great; āpa - obtained; nirvṛtim - jubilation.

When Hiraṇyakaśipu saw that his child had fallen at his feet and was offering obeisances, as an affectionate father he immediately began showering blessings upon the child and embraced him with both arms. A father naturally feels happy to embrace his son, and Hiraṇyakaśipu became very happy in this way.
