The Buddha of the present historical period is known as the Buddha Śākyamuni.

Eight Stages of the Path of Buddhas

In all world systems the careers of all Buddhas share the following eight stages:
1 Descending from the Tuṣita Heaven
2 Entering the womb
3 Emerging from the womb
4 Leaving the home-life
5 Subduing Māra
6 Becoming a Buddha
7 Turning the Great Dharma Wheel
8 Entering nirvana

“Who is the Buddha? The Buddha is the Greatly Enlightened One. His great enlightenment is an awakening concerning all things, without a single bit of confusion. A true Buddha is without karmic obstacles and has transcended emotional responses. Living beings, on the other hand, are attached to emotions and worldly love.” (AS 2)

“You still don’t know who the Buddha is? I will tell you. You are the Buddha. ‘Then why don’t I know it?’ you ask. Your not knowing is just the Buddha. But this is not to say that you have already become a Buddha. You are as yet an unrealized Buddha. You should understand that the Buddha became a Buddha from the level of being an ordinary person. Living beings have the ability to cultivate and become Buddhas. A Buddha is an Enlightened One; therefore, when a human being becomes fully enlightened, he will be a Buddha too.” (AS 4-5)

“When someone heard it said that the Buddha is living beings and living beings are the Buddha, he was really delighted. After that, he told everyone to call him Buddha. ‘Don’t call me by my name, just call me Buddha, because living beings are Buddhas!’ Then some people started calling him ‘Buddha,’ but because there were others who did not, he became irate and said, ‘I told you to call me Buddha. Why aren’t you calling me Buddha? I’m going to give you a hard time!’ Then someone said to him, ‘The Buddha is kind. In his heart there is compassion for all living beings; he doesn’t get angry or afflicted. If you were a Buddha, you would not have a temper or any afflictions. Because you still have a temper and afflictions, you are still an ordinary living being.’” (FAS Ch7 33)
