jahāsa bhīmas taḿ dṛṣṭvā
striyo nṛpatayo pare
nivāryamāṇā apy ańga
rājñā kṛṣṇānumoditāḥ
jahasa -- laughed; bhimah -- Bhima; tam -- him; drishtva -- seeing; striyah -- the women; nri-patayah -- kings; apare -- and others; nivaryamanah -- being checked; api -- even though; anga -- my dear (Parikshit); rajna -- by the King (Yudhishthira); krishna -- by Lord Krishna; anumoditah -- approved.
Srila Visvanatha Cakravarti mentions that King Yudhishthira tried to check the laughter by glancing at the women and Bhima. Lord Krishna, however, gave approval with a gesture of His eyebrows. The Lord had come to the earth to remove the burden of wicked kings, and this incident was not unrelated to the Lord's purpose.
