Krishna knows the human mind. Not everyone can lock their attention on the divine in one attempt. So He offers the second rung: if you cannot hold your mind steady in Me, then try to reach Me through abhyasa yoga — the yoga of repeated practice. Bring the mind back, again and again and again.
Anyone who has learned to ride a bicycle understands this. You fall. You get up. You try again. Slowly, balance comes — not because someone handed it to you, but because you kept showing up. That is abhyasa yoga. The mind wanders away from Krishna; you bring it back. It wanders again; you bring it back again. Over time, the wandering shortens and the steadiness deepens.
