According to both Bronkhorst and Anderson, the four truths became a substitution for prajna, or "<answer>liberating insight</answer>", in the suttas in those texts where "<answer>liberating insight</answer>" was preceded by the four jhanas. According to Bronkhorst, the four truths may not have been formulated in earliest Buddhism, and did not serve in earliest Buddhism as a description of "<answer>liberating insight</answer>". Gotama's teachings may have been personal, "adjusted to the need of each person."
