Shakyamuni Buddha

 With Shakyamuni Buddha, there was His emergence in the world with His realising that

 "Only I recognise the true character of things, as is also with Buddhas everywhere."

 This is equivalent to the time when,

"I, along with all Buddhas everywhere, having fully awakened to the True Matter, desire to help sentient beings open up to It, manifest It, awaken to It and enter It."

Dogen

12th century Japanese monk
