No, they are equivalent. The duality between Bodhisattvas and Arahants is the last duality.

All dualities are of the mind. They’re all based on comparisons. I’m good, but this person is bad. I’m beautiful, this person is ugly. I’m humble, they’re arrogant. You either love yourself (selfish), or others (altruistic).

Both Bodhisattvas and Arahants realized Nirvana, but both are separated from others by Nirvana. Nirvana is their last delusion, the last duality. They’re in Nirvana, others are not. They just ended up on two different sides of this duality. Bodhisattva’s Nirvana is for others, Arahant’s Nirvana is for him. So Bodhisattvas spend time and effort to help others realize Nirvana, and Arahants spend time in isolation, they prefer solitude.

All the petty differences between people based on which prior relationships formed have been transcended by that point. Only the last difference remains, and it becomes the basis of the last relationship - whether others are in Nirvana or not. Arahants are selfish in this relationship (“my Nirvana is for me, they don’t get it”), Bodhisattvas are altruistic (“my Nirvana is for others, I must help them”). In all dualistic relationships the arrow always must point either to you or to others. Of course, neither can see it, otherwise it wouldn’t be a delusion. That’s the source of the historic conflict between them.

But this conflict, like all dualistic conflicts, is not a real conflict. This relationship is also empty, this distinction is also empty. Both Bodhisattvas and Arahants must transcend Nirvana to become a Buddha. Buddhas don’t see a difference between Nirvana and Samsara, which is why Buddhas’ Nirvana is often times called non-abiding. Thus, Buddhas don’t see a difference between Bodhisattvas and Arahants, they are beyond both and they see them as equivalent in their realization.

That’s why Osho said once: “Bodhisattvas and Arahants know the Buddha but they are not yet the Buddha”. That was my experience also. Personally, I just couldn’t decide what to do with this freaking Nirvana, that is, should I just enjoy my life or should I help others. And I tried to, but no one really listened to me. So I was a pretty sucky Bodhisattva lol. A failed one hahaha. Successful Bodhisattvas can feed off their compassion for a very long time. So I was jumping back and forth between compassion and isolated self-enjoyment until I worked through all of my compassion and realized that the distinction between Nirvana and Samsara is also empty, as well as the distinction between realized people and not realized people.

That is also why a Buddha is a Tathagata - thus gone, thus come. He transcends Nirvana to return ordinary to the world. Bodhisattvas and Arahants are gone, but they have not yet come.
