Bhagavad Gita · Vishvarupa Darshana YogaChapter 11, Shloka 34 (11.34)

Shankaracharya. yeṣu yeṣu yodheṣu arjunasya āśaṅkā tāṃs tān vyapadiśati bhagavān — the Lord names each of the warriors Arjuna was anxious about; the reasons: Drona — dhanurvedācāryaḥ … gariṣṭhaḥ; Bhishma — svacchandamṛtyuḥ (death only at his own will); Jayadratha — his father's boon; Karna — the amogha śakti (unfailing spear) given by Indra; mā vyathiṣṭhāḥ tebhyaḥ bhayaṃ mā kārṣīḥ.

Acharya Ramanuja. gurūn bandhūn ca … kathaṃ haniṣyāmi iti mā vyathiṣṭhāḥ — "How can I kill my teachers and kin?" — do not be distressed by this; dharmādharmabhayena bandhusnehena kāruṇyena ca mā vyathāṃ kṛthāḥ; and the commentary's conclusion: yataḥ te kṛtāparādhāḥ … na eteṣāṃ vadhe nṛśaṃsatāgandhaḥ — because they have already done wrong, there is not a trace of cruelty in slaying them.

Madhusudana Saraswati. An analysis of Arjuna's fear: Drona — brāhmaṇottamo dhanurvedācāryo mama guruḥ; Bhishma — svacchandamṛtyuḥ, who dies only at his own will, whom even Parashurama could not defeat.

Shridhar Swami. The answer to the doubt of 2.6 (na caitad vidmaḥ kataran no garīyaḥ) is here: sāpi na kāryety āha — do not hold even that doubt.

Madhvacharya. Why Jayadratha is specially mentioned: because of his father's boon — whoever made his head fall to the ground, that person's own head would burst (from the story).
