BG 1.19 (1972), Translation and Purport

The blowing of these different conchshells became uproarious, and thus, vibrating both in the sky and on the earth, it shattered the hearts of the sons of Dhṛtarāṣṭra.

When Bhīṣma and the others on the side of Duryodhana blew their respective conchshells, there was no heart-breaking on the part of the Pāṇḍavas. Such occurrences are not mentioned, but in this particular verse it is mentioned that the hearts of the sons of Dhṛtarāṣṭra were shattered by the sounds vibrated by the Pāṇḍavas' party. This is due to the Pāṇḍavas and their confidence in Lord Kṛṣṇa. One who takes shelter of the Supreme Lord has nothing to fear, even in the midst of the greatest calamity.
