Let me explain Buddhism in this way:

The universe is God, the divine - called the Dharmakaya in Philosophical Buddhism and personified as Amida Buddha in the Pure Land Tradition.

Everything is part of the universe and so part of God.

Everything is Divine, including ourselves.

Everything has a divine nature, Buddhists call this the Buddha-nature.

This Divine is our true nature and real identity.

We are Buddha, the ego/self is just a character we are role-playing as the Divine Universe expresses itself.

Mindfulness of the Buddha, through the chanting of mantras, is simply Mindfulness of the Divine and our own divine nature, and thus liberation from the illusion of Self.
