About Amitabha, God our Father in Heaven
The Sanskrit word Amitābha is an honorary title used for the King of our spiritual world Sukhāvatī (Skt.), situated in the stellar system Sirius (Skt. Margavyadha).
The term Amitābha combines two Sanskrit words अमित(amita), which translates as immeasurable and भा(bha)(abha)(abhati), which translates as light.
Lord, or King Immeasurable Light is the ruler of the spirit-heaven known to us as Sukhāvatī. His title speaks to the bright light that flows from him. Humans learned about Amitābha in the 1st century, a time when the Hellenistic and Greco-Roman gods were still very active. Hellas, the sun god was the god of light of that era and some may have been ready to once-again syncretise the gods but there was a major difference between the fierce creator god Hellas and King Immeasurable Light. The King is not creator of the material world, does not interfere in it, and is a creature himself.
Amitābha is an ancient spiritual being who, at some point in time aeons ago, was but a soul being like us. It was long ago, before this Earth school was in operation, perhaps in other worlds, on a different planet. One of the honorific titles of the Amitābha is Tathágata, which means “one who has thus gone” or one who has walked this path of ours. Amitābha rose through the ranks of spiritual growth until he/it (spiritual beings have no gender) became what some call a perfected all-wise spiritual being, therefore a Buddha, a god. From that station, Amitābha increased in spiritual powers and stature to rise to intergalactic supreme status. He became the head of the splendorous spiritual world of social caregivers, Sukhāvatī.
The Unnameable One is the source and essence of all things seen and unseen. Therefore, It is also the source and essence of all types of spiritual beings, some of which we refer to as deities, gods (senior spiritual beings), and senior Gods (exceptionally powerful Divine Beings in charge of spiritual 'worlds').
The Unnameable Almighty One is the essence that animate and empower all things, also spiritual beings.
One such a majestic and powerful spiritual being is the ruler and monarch of our spiritual heaven, the Lord our God Amitabha, God our Father in Heaven.
The Sanskrit title Amitabha (sometimes abbreviated by Chinese people as Amita) means Eternal Light.
Our Father is in charge not only of the heaven called Sukhavati (Land of Bliss) in Sanskrit, but also of the soul school here on Earth. See article: Soul School Earth.
Various Scriptures east and west (Lotus Sutra, Heart Sutra, Bible, Eastern Bible, among other) state that Sukhavati is a monarchy, and our Father in Heaven is the King of Heaven and Earth. These Scriptures also speak of Avalokiteshvara as the son of God, the 'Savior of the World' as the 'Prince of Heaven', the one who would follow in the Father's footsteps as the future King of Sukhavati.
It is said that quite recently, about 15,000 years ago, Amitabha modified the genetic code of a humanoid strain animals on Earth to improve their physical bodies and minds to be better suited as soul vehicles in the school on Earth. For that reason it is said that God the Father is our maker, and knows us intimately. Students of the evolution of humanoids on Earth appreciate that after the previous glacial event on Earth a major jump in evolution is noticable, so much so that some scholars hypothesized an unsolved "missing link" theory. Such scholars may not have studied our traditional knowledge on this matter.
