atha cittaṃ samādhātuṃ na śaknoṣi mayi sthiram |abhyāsayogena tato māmicchāptuṃ dhanañjaya ||
But if you cannot hold your mind steadily fixed on me, then seek to reach me, O Dhananjaya, through the discipline of practice.
Explanation
Krishna has just told Arjuna to rest his mind and intellect wholly in him. Now he offers a more realistic step for those who find that too hard: steady, repeated practice (abhyāsa-yoga), meaning the effort of bringing the wandering mind back again and again. Commentators differ on whether this practice is meditation, devotional remembrance, or a mix, but all agree it is a gradual path.
