It is that one embodiment Christ said
“I am alpha and omega, the beginning and the end” 
The kingdom of God is within you – Gospel of Luke

It is that one embodiment Muhammed (pbuh) referred as
“I existed even before the creation and shall remain after its assimilation”

He who knows himself, knows me (God) – Muhammed (pbuh)

It is the same embodiment which spoke through Krishna (pbuh) saying
“We appear on earth then Dharma is corrupted”
