worship, adore, pray to
拜 centers on acts of deep reverence: worshiping, adoring, or praying to a deity or higher power.
拜 is the traditional form of 拝. It combines a hand-related left component with a right side that likely depicted a kneeling or bowing figure, expressing worship or prayer.
The left side looks like a hand, and the right side resembles a person bowing deeply. Picture hands pressed together in prayer as you bow in worship.
For ハイ, imagine a worshiper bowing and saying 'Hi' to a deity: Hi -> ハイ, a reverent greeting.
