Bodhisattva Precepts
At my last retreat, we recited the Bodhisattva vow quite frequently.

Sentient beings are numberless; I vow to save them. Desires are
inexhaustible; I vow to put an end to them. The Dharmas are boundless;
I vow to master them. The Buddha Way is unattainable; I vow to attain
it.

Not the precepts themselves, which were only recited by a preceptor when the precepts were being taken.
I would advise against regularly intoning them; it's an interesting question whether we can take them unofficially. Why not recite the nembutsu instead?
