Awakening during brahmamuhurta is considered the best time for arising from slumber, from a natural and spiritual perspective. During these early morning hours, roughly from 3 a.m. to 6 a.m., the environmental potency makes spiritual practice immensely powerful. In the Judaic scriptures, Moses built an altar to God in those early morning hours, demonstrating the numinous force of the early morning:
Exodus 24:3-5: When Moses went and told the people all the LORD's words and laws, they responded with one voice, "Everything the LORD has said we will do." Moses then wrote down everything the LORD had said.
He got up early the next morning and built an altar at the foot of the mountain and set up twelve stone pillars representing the twelve tribes of Israel. Then he sent young Israelite men, and they offered burnt offerings and sacrificed young bulls as fellowship offerings to the LORD.
