Bhagavad Gita · Chapter 6: The Path of Meditation
Bhagavad Gita 6.39
एतन्मे संशयं कृष्ण छेत्तुमर्हस्यशेषतः ।
त्वदन्यः संशयस्यास्य छेत्ता न ह्युपपद्यते ॥
etanme saṃśayaṃ kṛṣṇa chettumarhasyaśeṣataḥ | tvadanyaḥ saṃśayasyāsya chettā na hyupapadyate ||
You should remove this doubt of mine completely, Krishna. No one other than you can be found to remove it.
Modern context
Arjuna asks Krishna to cut this doubt completely, because no one else can. There is wisdom in knowing whom to ask. Some questions cannot be answered by just anyone; they need someone who has walked the road. It is worth noticing who in our own lives can actually resolve our deepest doubts, and taking our questions to them rather than circling them alone.
