In a religious practice following a faith and texts that are revealed rather than rational thinking, questioning can not take place, as inquiry is taboo and doubts are irreverent, unacceptable and they will be considered blasphemous. The spirit of inquiry, doubts and questioning are the very foundation of science, technology, literature and any historical investigation. In a true perspective, questioning indicates modesty and ignorance, whereas total acceptance of what is said indicates that you are sure of what you are learning, or may be just a blind faith of a dogma. "So it is Written; so it shall be Done." Hinduism, from ancient days, permits its devotees to study the teachings, accept different meanings and interpretations, question, reason and analyze what is being taught as Truth. This has given a greater understanding and improvement of the religious practice and made the faith and the teachings stronger. It accepted adjustments to accommodate these new ideas and made Hinduism much stronger faith among its followers.

Any theory proposed by the Hindu leaders that was not accepting "God" as supreme was rejected. Strong objections and alternate thoughts and beliefs, at times, created splinter groups and new religious branches. Often the conflicts occurred between the various paths of approach to Vedic teachings and interpretations. Often when rituals became popular to lead to a blind following, philosophy and principles had to be established. As early as in the period of Srimad Bhagvat Gita, Sri Krishna objected to pure ritualistic practice and put the philosophy in the forefront. Later Gautama Buddha revealed the same and opposed to rituals. He also opposed the concept of God and teachings of Vedas and this lead to the start of Buddhism. As his teaching were becoming popular, some Hindus started accepting Him for His good teachings of ahimsa. He became one of the ten important Incarnations of Mahavishnu. About the same time, Sri Mahavira established a faith as Jainism. Both these religions accepted a Master and his teachings without accepting or describing the form of a Supreme Divine force as God or prescribing any "Vedic rituals" to Him.
