“So at all times remember me, and fight on.”

Bhagavad Gita 8.7
In plain terms

In the story Krishna asks Arjuna to hold him in mind and keep fighting, both at once. The instruction is double on purpose: remembrance without withdrawal, effort without forgetting what it is for.

In an ordinary week it reads as a way of working: keep the deepest thing you know present in the background while your hands stay busy in the foreground.
