Bodhisattva precepts are the cultivation foundation for bodhisattvas. Only after taking the precepts can one become a true bodhisattva, and only a true bodhisattva can become a Buddha. Therefore, taking the precepts is a prerequisite to becoming a Buddha. All Buddhas in the past, present, and future become Buddhas only after having taken the precepts. Hence, the bodhisattva precepts are also called the great precepts of a thousand Buddhas.
