Countless buddhas in the past, including Shakyamuni Buddha, vowed to liberate all sentient beings when giving rise to bodhicitta, vowing to attain buddhahood after all sentient beings attain buddhahood. We haven’t attained buddhahood yet, but they have. Why? Buddhas make such aspirations out of vast compassion. Due to the greatest and sublimity of their aspirations, they attained buddhahood swiftly. Whereas we are preoccupied with our own interest, thus we are still struggling in the samsara.
