Buddhism emerged from the highly developed religious Hindu society. Many teachings of Gautama Siddhartha, the Buddha, are found in or are similar to the teachings of the Upanisadic sages.
Gautama found the secret of sorrow and at last understood why the world is full of sufferings and unhappiness, and what man should do to overcome them, through the deep meditation under the bodhi tree. Thus he was fully enlightened and became a Buddha.
Buddha is said to have preached to his disciples in the Deer Park. The teachings include the "Four Noble Truths", and the "Noble Eightfold Path" which are accepted as basic doctrines by all Buddhist sects.
". . . this is the Noble Truth of Sorrow. Birth is sorrow, age is sorrow, death is sorrow, contact with the unpleasant is sorrow, separation from the pleasant is sorrow......"
". . . the Noble Truth of the Arising of Sorrow...... thirst, which leads to rebirth, which brings delight and passion, and seeks pleasure now here, now there -the thirst for sensual pleasure, the thirst for continued life, the thirst for power."
". . . this is Noble Truth of the Stopping of Sorrow. It is complete stopping of that thirst, so that no passion remains, leaving it, being emancipated from it, being released from it, giving no place to it."
". . . this is Noble Truth of the Way which Leads to the Stopping of Sorrow. It is the Noble Eightfold Path - Right Views, Right Resolve, Right Speech, Right Conduct, Right Livelihood, Right Effort, Right Recollection and Right Meditation."
To Buddhist, the universe is sorrowful and transient. The only stable and peaceful entity is Nirvana, the state of bliss reached by the Buddhas and Arhants (one who realized Nirvana) or perfected beings. Some scholars interpreted Nirvana as a state of complete annihilation. However, Buddha just said, "I have not said that the Arhant exists after death, and I have not said that he does not exist......" This statement suggests that the Nirvana is outside this universe, transcending both being and non-being.
