Truth means Absolute Truth. Relative truth is conditional and when the conditions fail, the relative truth disappears. But Absolute Truth does not exist on conditions it is above all conditions. So when we speak of truth, we may take it for the Absolute Truth. And when we speak of approaching the Truth by new ways, we may take it for granted what we want to approach the Truth by the inductive way.
Absolute Truth is described in the Vedas as Satyam Param Dhimahi—the summum bonum. And from this Absolute Truth everything emanates. "Janmadyasya yatah". This Absolute Truth is described in the Vedic literatures as Sanatana or Eternal. And the philosophy or science which deals in such eternal subjects is described as Sanatana Dharma.
Therefore, we have first to find out the Eternal Absolute Truth by some new ways(?) and then we have to find out the new aspects of Absolute Truth in harmony with our present environment.
