Bhagavad Gita 6.33
योऽयं योगस्त्वया प्रोक्तः साम्येन मधुसूदन। एतस्याहं न पश्यामि चञ्चलत्वात् स्थितिं स्थिराम्॥
arjuna uvācha yo ’yaṁ yogas tvayā proktaḥ sāmyena madhusūdana etasyāhaṁ na paśhyāmi chañchalatvāt sthitiṁ sthirām
Translation
This yoga which Thou hast declared to be by equanimity, O Madhusûdana, I see not a stable foundation for it, owing to restlessness;
What it means
Arjuna objects honestly: this yoga of equanimity seems to have no stable footing, because of the mind's restlessness. The student's difficulty is legitimate. A teaching that ignores the mind's nature would fail.
Try this today
Arjuna objects on behalf of everyone who has tried: the theory is beautiful, but minds do not hold still.
Something to reflect on
What do I find hardest to hold steady?
