"There are a vast amount of Buddhas already, and each one manifests countless forms simultaneously throughout all of the planes of cyclic existence for the benefit of all beings. However, at any given time, each individual being will have a stronger karmic connection with certain Buddhas, compared to other Buddhas.
Likewise, if you were a Buddha, since a huge number of beings throughout cyclic existence would have a stronger karmic connection with you during certain times, you would be able to benefit them much more directly than the many other Buddhas would be able to. Do not forget this.
The deeper you realise this, the greater your bodhicitta motivation becomes - in other words, the greater your compassionate wish to attain the enlightened state of a Buddha for the benefit of all beings, as soon as possible!"
