The Buddhavamsa is quoted on our Buddha's bodhicitta intention, made long, long ago. This intention can be made now by any who are qualified.
"When he initially invited the Buddha and his disciples to use him as a
bridge across the mud, Sumedha was focused on his own welfare. He knew
that if he wished, he could eradicate defilements and become an arahant
that very day by listening to a discourse by Buddha Dīpaṃkara. Questioning
his self-centered intention, he made an unshakable resolve to become a
buddha and lead all other beings out of saṃsāra (Bv 55–58):
What is the use while I remain ignorant of realizing Dhamma
here? Having reached omniscience, I will become a buddha in
this world with its devas. What is the use of my crossing over
alone, being a person aware of my strength? Having reached
omniscience, I will cause the world together with its devas to
cross over.
By my merit toward the supreme among humans, I will reach
omniscience; I will cause many beings to cross over. Cutting
through the stream of saṃsāra, shattering the three renewed existences,
embarking in the ship of Dhamma, I will cause the world
with its devas to cross over."
