Bhagavad Gita Chapter 12, Verse 9

अथ चित्तं समाधातुं न शक्नोषि मयि स्थिरम् | अभ्यासयोगेन ततो मामिच्छाप्तुं धनञ्जय ||

atha cittaṁ samādhātuṁ na śaknoṣi mayi sthiram abhyāsa-yogena tato mām icchāptuṁ dhanañjaya

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

Krishna provides an alternative path for those who find it difficult to fix their mind steadily. 'Atha cittaṁ samādhātuṁ na śaknoṣi mayi sthiram'—if (atha) you are unable (na śaknoṣi) to fix your mind (cittam samādhātuṁ) steadily on Me (mayi sthiram). 'Abhyāsa-yogena tato mām icchāptuṁ dhanañjaya'—then (tataḥ) seek to attain Me (mām icchāptuṁ) by the yoga of practice (abhyāsa-yogena), O Arjuna (dhanañjaya). This verse acknowledges that not everyone can immediately fix their mind steadily. For those who struggle, Krishna offers the yoga of practice (abhyāsa-yoga)—regular practice that gradually develops the ability to focus. This is compassionate guidance: if direct focus is difficult, practice regularly. Verse 12.10 will provide another alternative for those who still find it difficult.
