Buddha is one of the Ascended Master essences. These essences support experiencing the consciousness, energy and teachings of the Ascended Masters. In this context the Buddha is not a person but a consciousness. 

The Buddha essence brings to us the energies of compassion, grace, and oneness. This essence offers the energies of non-resistance, awareness of impermanence, and deep compassion. 

We are told that the only difference between Buddha, every other Ascended Master and us, is that they have awakened fully into the truth of their Divinity while we still slumber. For in each of us is the spark of potential, the seed of our Divine nature. It is hoped for that through this essence we can regain the memory of our own Divine Identity and manifest the Buddha consciousness in our lives.
