A lie is always a lie, whether it is black or white. And killing is always wrong, whether the object of murder is an innocent child, or one as notorious as Hitler. Spirituality is a level of consciousness that transcends rationality. While a philosopher may reach the peak of the rational world of reason by opposing the irrational, a prophet becomes a sign post in the non-rational world of Spirit. The predominant feature that a prophet possesses, which a philosopher lacks, is the element of faith.
Faith is something which transcends reasonableness, rationality, and even emotions.
All prophets possessed this faculty to a great extent. They had faith in the existence of a higher power, and an eternal mode of being. They recognized our physical mortality, yet they also believed that death was simply a doorway to another dimension. In short, all prophets believed if we maintain our faith and spiritual belief, and if we respond accordingly in our lives, then somehow, sooner or later, this Universe will progress towards its desired end. The path of Asha is an extreme path.
