śhrutvā

आश्चर्यवत्पश्यति कश्चिदेन माश्चर्यवद्वदति तथैव चान्यः

śhrutvā — having heard

One person sees it as a wonder; another speaks of it as a wonder; another hears of it as a wonder — and even having heard, no one truly knows it.

एतच्छ्रुत्वा वचनं केशवस्य कृताञ्जलिर्वेपमानः किरीटी

śhrutvā — hearing

Hearing these words of Krishna, Arjuna joined his palms, trembling, bowed down, and spoke again — stammering, in great fear.

अन्ये त्वेवमजानन्तः श्रुत्वाऽन्येभ्य उपासते

śhrutvā — by hearing

And others, not knowing this, hear it from others and worship. They too cross beyond death, holding to what they have heard.
