The Upanishads contain the highest form of philosophical introspection
in Hinduism and and are seen as perennial sources of spiritual
knowledge.
There are ten principal
Upanishads.
For a more rigorous philosophical discussion about
truth, consult philosophy textbooks, e.g., M. Velasquez, Philosophy: A Text with Readings, 6th ed. (Belmont: Wadsworth
Publishing Company, 1997).
In the Bahá'í writings, terms such as ``Sun of Truth''
refer primarily to the Manifestations of God, e.g. Jesus, Krishna,
etc. See Chapter 3 for details.
Parallels between romantic and erotic desire on
the one hand, and passion for truth and God on the other, can be found
not only in Eastern philosophy and mysticism, but also in Western
radical theology. Søren Kierkegaard, for example, gave
emphasis on one's relationship to God rather than on rational
objective analysis. See M. Velasquez, Philosophy: A Text with
Readings, 6th ed. (Belmont: Wadsworth Publishing Company, 1997).
