Gist of the sloka:
That which is full, will be motionless; like the ocean which will not overflow even when the mighty rivers flow into it. One in whom the mind is still, will not get disturbed when the various temptations enter him. He achieves mukthi. Not the one who is behind bad desires.
Lord Krishna is giving more detailed information regarding the seeker who has seen Him and seekers behavior. The seekers mind will always be in still and in constant state of happiness. It will be forever in Lord thoughts and glory. His mind will be still like a ocean neither overflowing nor shrinking. Similar to ocean which does not shrink in summer nor overflow in rainy season.
Even when the worldly temptations enter into his mind, they will not disturb his mind, for he is above happiness/grief. He will be at peace. With his concentrated mind, he will achieve Lord. Whereas the one behind various temptations and desires will never reach Him and never find peace.
