In Shantideva’s Bodhisattvacharyavatara, a bodhisattva is defined not by status, birth, or even present realization, but by bodhicitta—the altruistic intention to attain complete enlightenment for the sake of all sentient beings. The decisive shift occurs at the moment this authentic intention arises: when a being sincerely resolves to awaken so that others may be freed from suffering, that being is regarded as a bodhisattva, regardless of current spiritual attainments. What marks this figure is the universal scope of concern, a willingness to seek buddhahood not for personal liberation alone, but in order to assist all beings in escaping suffering. The bodhisattva thus takes on a vast responsibility, oriented toward the welfare and liberation of every sentient being.

Shantideva further clarifies that this defining bodhicitta has two complementary dimensions. There is aspirational bodhicitta, the heartfelt wish and commitment to attain enlightenment for the benefit of all, and there is engaged bodhicitta, the active undertaking of the bodhisattva’s conduct. This engaged dimension expresses itself through the systematic cultivation of the six perfections—generosity, ethical conduct, patience, effort, concentration, and wisdom—practiced with the explicit motivation of benefiting others. In this way, the bodhisattva is not merely an ideal of compassion and wisdom, but a practitioner who translates intention into disciplined action.

From this perspective, the bodhisattva may be understood as a being whose inner orientation has been radically reoriented from self-centered aims to an all-encompassing altruism. The defining qualities are a stable, compassionate motivation, the resolve to attain buddhahood for others, and the commitment to live in accordance with that resolve through the bodhisattva path. Such a being is characterized by compassion and wisdom, and is described as willing to defer final personal liberation until all beings are freed from suffering. The bodhisattva ideal, as articulated by Shantideva, thus unites an expansive inner intention with a concrete, ethical, and contemplative way of life.
