Amitabha is the title of god our Father in Heaven to whom Iesous prayed calling on his "Light Father", or "Abha Father", in the Garden of Getshemane, as recorded in the Christian New Testament.*
Wayist scholars and devotees make liberal use of the various meanings of the word Amitabha. Several treatise have been written on the deeper meaning portrayed by the various meanings. Depending on one's disposition or need at the time, the following meanings of the title Amitabha are considered correct: Infinite Light, Infinite Appearance, and Immesuarable Beauty.
Author Jean duPlessis expounded this concept in his book Universal Gateway of Enlightenemt
infinite, immeasurable, boundless, unmeasured, without a certain measure, immensely
appearance, light, resemblance, splendour, beauty, lustre, glamour, reflected image, flash, blaze, colour
Amitabha is the King of Sukhavati, a "spiritual heaven" in human terms. In Wayism and Mahayana Buddhism, those spiritual beings who are destined to and hail from Sukhavati are referred to as the Lotus Family, of which Amitabha is the Father.
Humility, Simplicity and Compassion are the three central qualities of Wayism. Amitabha Father displays all three these qualities. The King's simple clothing and lack of adornements, the colour of compassion (red) glows in his aura, and the meditation mudra, hair tied in a bun on top of the head, sometimes with an unja showing, and seated on a lotus throne—all these are the iconographic elements reserved for Amitabha. This combination of iconographic elements is not shared with another deity in Mahayana.
To the above essential iconographic elements one may add a begging bowl to illustrate non-attachment, and a Ajna chakra symbol between the eyebrows, a halo.
Amithaba is not prominent in Theravada. In SE Asia, Theravadins often use iconography of Amitabha to also depict Gautama Buddha. Another, more legitimate usage is when they use the exact same iconographic depiction but with the right hand touching the floor, in the mudra of Gautama Buddha calling the Earth to Witness.
Often seen with Amitabha are the two figures of Avalokiteshvara on the Lord's right and Mahasthamaprapta on the Lord's left. This Heavenly Trinity is the Wayist Trinity. It forms the foundation of the Wayist cosmology in that it depicts what we understand about the purpose of life, the process of enlightenment, the future existence as spiritual beings and the ministry of Iesous (Jesus in Roman language).
Avalokiteshvara is the spiritual being who is the so-called 2nd coming of Iesous as Saviour of the World in c.78CE, a Sanskrit title bestowed on Avalokiteshvara in Mahayana scripture.
