But God is, in the highest sense, one: formless (no material form, only spiritual/transcendental), infinite, and eternal.
Being formless, God is genderless (Vishnu is male, but can accept the female form of Mohini).
But beyond the mere mention of the 'term' several times, no longer description is provided for the word (Ekam is similar to Ek-Omkar (One AUM) of Sikhism).
Strengthening this view, a series of quotes from Arul Nool portraits Vaikundar as eternal and reveals his Universal form.
The mythical narrative speaks of Sivam (matter) and Shakti (energy) as the next evolved powers from the supreme Ekam.
But in Kali Yukam, due to the cruel nature of the boons offered to Kaliyan, Thirumal (the then supreme power) cannot destroy the sixth fragment of Kroni directly so all God-heads were unified into the Ekam, and Ekam Incarnated in the world as a Turine god (Ekam, Narayana and Human) in the form of Vaikundar to overcome the boons and to destroy Kali.
Also the contents of Arul Nool, based on the teachings of Vaikundar, which were believed to be written by arulalarkal and Citars, is completely monistic.
For example, during the Vinchai, inside the sea, Narayana, seeing Vaikundar, says that "You are Sivan, you are Thirumal, you are Nathan, you are the Tapas, and you are the one who is omnipresent in all which exists".
Lord Narayana has the most important role in Ayyavazhi theology compared to any other God-heads from Hindu tradition.
The internal evidence states that the primary scripture of Ayyavazhi, Akilattirattu Ammanai was told by Narayan to his consort Lakshmi, which was heard by Hari Gopalan Citar.
Due to this action of Siva, Vishnu refused to incarnate in the world for destroying the final fragment of Kroni.
All these episodes — starting with his 'birth' at sea as the 'son' of Narayana, the performance of the grand Tavam, the symbolic shamanic actions of incinerating the demons, the seizing of esoteric powers, and the unifying of the deities unto himself — highlight the important message that Ayya Vaikundar came as the avatar of Narayana.
(see: Ayyavazhi Trinity) After the birth in the sea, Vaikundar was addressed by Akilam quite commonly as Narayana.
Then the aim of the austerity of seven virgins towards vishnu to marry them is fulfilled in the Vaikunda Avatharam by Vaikundar.
(see:Ayyavazhi Trinity) Right from the beginning of the Vinchai of Tiruchendur Vaikundar has been focused as the ultimate power or incarnation of the supreme Ekam.
All sort of administrations - Creating maintaining and destroying were all handled to Vaikundar through the Vinchai by Narayana, who was responsible for all these actions from the beginning of Kali Yuga.
The relations between the Ekam, Narayana and Vaikundar were understood as having different implications found in several verses of Ayyavazhi scriptures.
Another area in which Vaikundar has been high lightened as the supreme universal power is the Marriage with the deities.
