The previous shloka identified the problem: Maya deludes the world. Here comes the solution. This Maya, Krishna says, is Mine. It is divine in origin, made of the three gunas, and extremely difficult to cross through one's own efforts alone.
But — and this 'but' is the heart of the shloka — those who surrender to Me, they cross this Maya entirely. Like a powerful river that is impossible to swim across alone. But if you board the boatman's vessel, that same river becomes crossable. Krishna is the boatman.
'Mam eva ye prapadyante' — those who take refuge in Me alone. This is the call for single-pointed surrender. And there is compassion in how Krishna puts it. He is not saying 'figure it out yourself.' He is saying: don't struggle alone; come to Me, and I will carry you across.
