Ground is the term for of all of reality. It is "God". It has 3 parts to its nature.
Rang shin, luminous mind. Clarity, the basis of consciousness. Father.
Ngo Wo, emptiness, potential, ",pure energy", described as like a mirror, clear and void but has the capacity to reflect. Mother/Holy
Thug Je, energy from which all phenomenon manifest, like the son of the other 2. Conscious beings have the luminous mind, inanimate objects are of Ngo Wo purely. The word matter was derived from materia which was derived from Mater, Latin for mother.

Stop looking for something to worship so desperately, all of you. It's like you need it otherwise you think everything is meaningless and you give up, but the truth is far more interesting than fables. Worship and pray to the Father in the mindset that he is Deus-Pater, the luminous mind.

10 The disciples came to him and asked, “Why do you speak to the people in parables?”

11 He replied, “Because the knowledge of the secrets of the kingdom of heaven has been given to you, but not to them. 12 Whoever has will be given more, and they will have an abundance. Whoever does not have, even what they have will be taken from them. 13 This is why I speak to them in parables:

“Though seeing, they do not see;
though hearing, they do not hear or understand.

Jesus taught the mysteries to his disciples, and to everyone else he gave fables. This is where the "secret societies" come from, not any of the imagined bullshit about it being some secret cult opposed to Christianity. All those rumors do is serve to scare you into the arms of those who run the secret societies.
Jesus spoke of true things, but you're not getting their true meaning at church. Jesus' actual teachings have been kept within bloodlines, societies, and certain towns where everyone knows for thousands of years now.
I wish you all luck.
