Be practical in the real world

The Buddha always advised his disciples to not waste their time and energy on metaphysical matters. Whenever they asked him questions on metaphysics, he always remained silent. Instead, he asked them to focus on practical matters. One day, a disciple asked him about the infiniteness of the universe. “Whether the universe is infinite or finite, the problem of liberation remains,” the Buddha replied.
Often, our focus tends to be directed at matters that may not have a solution to our woes. In the practical world, it is wise to focus on practical things even if they do not help us liberate ourselves.
