In earlier Shloka Bhagvan Shri Krishna explained that delusion is a natural phenomenon for living beings, as this originate from nature, its modes(Satva, Rajasa, and tamas) and the duality of desires and aversion.

But the very obvious question arises, is there any way to get out of this delusion. The answer is, yes, there are ways and this Shloka gives the answer.

Bhagvan Shri Krishna explains a human has to purify his deeds and action, has to realize the truth that the material body is temporary. The ultimate truth is the supreme personality, Bhagvan
Shri Krishna. Engaging continuously into the devotion of Krishna human is able to come out of this delusion. If he is born as a human in the next birth he will be free from such delusion since his birth. But if not, he can start his pious journey into the path of Shri Krishna and he will acquire the pious state sooner or later.
