Bhagavad Gita 12.9

अथ चित्तं समाधातुं न शक्नोषि मयि स्थिरम्।अभ्यासयोगेन ततो मामिच्छाप्तुं धनञ्जय॥

atha cittaṃ samādhātuṃ na śaknoṣi mayi sthiram |abhyāsayogena tato māmicchāptuṃ dhanañjaya ||

If you are unable to fix your mind steadily on Me, then seek to reach Me through the yoga of constant practice, O Arjuna.

But if you cannot fix your mind firmly on Me, then, my beloved friend, try to do so through constant practice.

Our plain-language meaning of this verse is waiting for scholar review.
