Acharya Prashant explains that multitasking is an impossibility in reality because existence only allows for one thing to happen at a time. He emphasizes that whatever action is being performed must be done with one hundred percent focus and presence. He cites a Zen monk's wisdom, stating that when one eats, they should only eat, and when they walk, they should only walk. The mind often creates a phase difference by lagging in the past or jumping into the future, which prevents a person from being fully alive in the present moment.
