While these philosophies differ as to details, each represents an important
truth or insight also recognized by the others. These can be summarized as follows---
SANKHYA: Its fundamental
insight is the discrimination between Spirit and matter, the inner and the outer,
consciousness and form. This is the starting point of all spiritual teachings. It also
presents an ordering of cosmic principles according to the faculties of our nature and our
capacity for experience on different levels. This examination of the process of perception
and the nature of consciousness is followed by all systems.
YOGA: Its fundamental insight is the need for
practise and its outline of the eightfold or integral Yoga path. All these systems use
some form of Yoga and resort to some form of each of its eight limbs. All have their
attitudes and values, using Yoga postures, examine the breath, and teach meditation.
VEDANTA: Its fundamental insight is the sole
reality of the Self or the inner consciousness and the unreality of all we think is other
than it. It also stresses the truth of the absolute unity of all life. Dualistic Vedanta
emphasizes devotion and the need for the worship of the Divine.
