The mode of training in emptiness on the 5 Paths described in “The Heart Sutra” are:
(a) Path of Accumulation: Training involves the study and contemplation of the Perfection of Wisdom. The practitioner develops their understanding of emptiness in-terms of the 4 features of emptiness.
(b) Path of Preparation: Training involves meditation on the meaning of the Perfection of Wisdom, as well as continuing the practices from the Path of Accumulation.
(c) Path of Seeing: Training reaches the point where the practitioner is able to “see” emptiness directly. The practitioner realizes selflessness and abandons artificial mental afflictions. The practitioner becomes an Arya / Supreme being.
(d) Path of Meditation: The practitioner gains a subtle understanding of the mental afflictions to be abandoned through constant meditation.
Of the 10 Grounds, in the first through seventh grounds the practitioner abandons the innate, spontaneously arising mental afflictions; in the eighth through tenth grounds the practitioner abandons obscurations to knowledge which are the subtle imprints of mental afflictions.
(e) Path of No More Learning: The practitioner achieves the omniscient mind.
