What new questions the philosophers of Vedic tradition and outside were thinking in the 6th century B.C.E.?
The Upanishads are the texts of the Vedic tradition. They are the store-houses of many new ideas. They show that the people were curious to know the meaning of life. They were also eager to know about the possibility of life after death and rebirth. The issues of rebirth and the past deeds were hotly debated. All the Vedic thinkers were concerned to understand and express the nature of the ultimate reality. A few thinkers outside the Vedic tradition were also raising the question of whether the ultimate reality was single or plural. The people had also started speculating the significance of the sacrificial tradition. Hence, there was an emergence of a thoughtful environment.
