Bodhisattva (Tibetan: jang chub sem pa. English: heroic aspirant to enlightenment): The word bodhisattva from the Sanskrit language is a Buddhist technical term relating to motivation, qualification, and level of spiritual attainment. It is a primary term found in the Mahayana Sutras as practiced in Northern Buddhism (North India, Himalayas, Central Asia and East Asia) and its meaning is included in the definition of Mahayana Buddhism distinguishing it from other forms of Buddhism such as Theravada of South Asia.

Religious & Textual Definition:
As a religious term bodhisattva means a heroic aspirant to enlightenment. An individual becomes a bodhisattva by taking up the enlightenment thought (bodhichitta) through one of two standard rituals, sometimes called an ordination, following either of the paramount philosophical schools of Yogachara or Madhyamaka. A bodhisattva is a practitioner of the enlightenment thought which is the aspiration to achieve complete enlightenment as a perfect Buddha for the benefit of oneself and all other sentient beings in the universe.
Types of Bodhisattvas:
Based on spiritual attainment bodhisattvas are divided into two groups: first, there are ordinary people, men and women who are followers of Northern Buddhism that have participated in the ritual of the enlightenment thought and are now considered to be ordinary bodhisattvas. Second, there are the special students of the Buddha, special bodhisattvas, spoken of in the ancient Mahayana Sutras. Examples of these, referred to by the title of bodhisattva or great (maha) bodhisattva, are Manjushri, Avalokiteshvara and Maitreya. They are known as realized or enlightened bodhisattvas based on a system of ten levels, or grounds of spiritual realization, that progressively lead to complete enlightenment - buddhahood. The ordinary bodhisattvas, following the behaviour of the special bodhisattvas as examples, engage in a course of practice modeled on the system of these ten levels.
Three Special Bodhisattva Similes:
The aspiration to reach enlightenment for the benefit of all beings has three special similes to characterize three mental attitudes used in accomplishing the goal of enlightenment. They are King-like, Captain-like and Shepherd-like. The King-like attitude has the intention to lead beings by example and reach enlightenment first - bringing all beings safely along behind. The Captain-like attitude, just like a good ships captain, brings everybody on board together, and as a group safely crosses over to enlightenment. With the Shepherd-like attitude the flocks of beings are ushered ahead while the bodhisattva guides from behind. The bodhisattva Avalokiteshvara is famous for his discourses in the Mahayana Sutras on the Shepherd-like attitude. Shakyamuni Buddha as a bodhisattva was an example of the King-like attitude.
