एतन्मे संशयं कृष्ण छेत्तुमर्हस्यशेषतः। त्वदन्यः संशयस्यास्य छेत्ता न ह्युपपद्यते ॥

etan me sanśhayaṁ kṛiṣhṇa chhettum arhasyaśheṣhataḥ tvad-anyaḥ sanśhayasyāsya chhettā na hyupapadyate

Deign, O Krishna, to completely dispel this doubt of mine; for there is none to be found save Thyself able to destroy this doubt.

In plain words: Arjuna begs Krishna to clear away this doubt completely. He says no one but Krishna is able to answer it.
