Bhagavad-gītā As It Is · Text 12.9
Krishna describes devotional practice and progression
अथ चित्तं समाधातुं न शक्नोषि मयि स्थिरम् ।
अभ्यासयोगेन ततो मामिच्छाप्तुं धनञ्जय ॥ ९ ॥
atha cittaṁ samādhātuṁ
na śaknoṣi mayi sthiram
abhyāsa-yogena tato
mām icchāptuṁ dhanañ-jaya
My dear Arjuna, O winner of wealth, if you cannot fix your mind upon Me without deviation, then follow the regulative principles of bhakti-yoga. In this way develop a desire to attain Me.
