A ritual is magick in action!
It's like crafting a magick spell with people as the main ingredients. And like any good magick spell, it lifts the ingredients up from being ordinary to being Divine. Once you realize this, the practice of ritual makes intuitive sense.
The Purpose of any ritual is then obvious: to create change within ourselves, and thus, in the world.
The Means is perceiving spiritual reality, becoming one with it, and then transforming it.
The Process is shifting consciousness, applying intense focus and energy to what we desire, and calling it to us through symbolic actions.
The Outcome is that we are lifted into the Good Reality, the world we want to be part of.
