As Prof. M. Ranga
chariar says, in his Lectures on the Gita, second volume, page 117: " The history of
man, as lighted and explained by the associated modern auxiliary sciences gives ample
support to the view that the unfoldment of the power of the spirit is in reality the aim
of God's government of the universe and that this
unfoldment takes place more through ethical evolution than through what has, in contrast,
been called 'the natural evolution' that is, more through self sacrifice than through
self-assertion, more through altruism than through egoism."
Thus we realize that the enunciation and acceptance of moksha as the
supreme goal of life by Indian thinkers has given a unique direction to the whole
philosophy of life unparalleled in the history of thought in any other country.
Relation among the Purusharthas--Kama
Among the four purusharthas, moksha is mentioned
as the last as it is the supreme, or parama-purushartha. Next in order comes kama. There
is one feature common to both of these Moksha is supreme, unalloyed, eternal happiness,
while karma denotes the happiness or joy enjoyed by ordinary mortals in life. They both
have as already mentioned the element of happiness.
