This shloka brings the thread to its conclusion. The yogi who strives earnestly, life after life, gradually sheds every impurity. Over the course of many births — aneka-janma — the practice deepens, the understanding ripens, and perfection is reached. Then comes the supreme destination: param gatim.
The phrase 'aneka-janma-samsiddha' is worth sitting with. Many births. Not one. Not two. Many. Krishna is describing a long road. But the destination is certain. Every step taken in any lifetime counts toward the final arrival. No step is lost. No effort dissolves.
This is the complete answer to Arjuna's fear. The torn cloud does not vanish. It gathers again, grows, and eventually brings rain. The journey may span lifetimes, but it ends in the supreme — param gatim.
