The Meditation Practice of the Holy Trinity
A very simple yet powerful meditation involves becoming aware of the Holy Trinity of Mother Earth, Father Sky, and God or an all-encompassing greater presence within you.
First collect up your sense of love. Imagine whatever it takes for you to move into a state of love. For instance, remember an instance where you felt strongly for someone or an animal. Bundle this experience up and send it to the Earth. Wait for it to send it back to you. Maintain this connection with Mother Earth.
Collect up a strong sense of love again and send it to the Cosmos or to everything that is not Mother Earth. You can also call this part of reality Father Sky. Wait for him to send it back to you. Maintain this connection with Father Sky and Mother Earth.
Allow yourself to become aware of a third all-encompassing presence (God seems more readily accessible while connected to Mother Earth and Father Sky than at most other times). Send your love to her and wait for it to come back to you.
Be aware and experience your connection to each, Mother Earth, Father Sky, and God, simultaneously. You have now made the Holy Trinity manifest within yourself. Stay in this state as long as possible.
By the way, this is a great way to start any meditation practice or sacred ceremony; this is of course, after doing the Banishing Ritual of the Pentagram.
