(The Buddha)
What are the five wildernesses in the heart which are to be abandoned?
Here one is doubtful, uncertain, undecided, and unconfident about :
1. The teacher…
2. The dhamma…
3. The sangha…
4. The training…
5. If one is angry, displeased with his companions in the holy life, resentful and callous towards them…
…and thus the mind does not incline to ardour, devotion, perseverance, and striving – these are the five wilderness in the heart that are to be abandoned.
What are the five shackles in the heart that are to be severed?
Here one is not free from lust, desire, affection, thirst, fever, and :
1. craving for sensual pleasures
2. craving for body
3. craving for form
4. eating as much as one likes until the belly is full and then indulging in the pleasures of sleeping, lolling, and drowsing…
5. aspiring to some order of the gods thus: ‘by this virtue or observance or asceticism or holy life, I shall become a [great] god or some [lesser] god,’…
…and thus ones mind does not incline to ardour, devotion, perserverance, and striving – these are the five shackles of the heart to be severed.
Any one who has abandoned these five wildernesses of the heart and severed these five shackles in the heart can come to growth, increase and fulfillment in this Dhamma and Discipline.
One develops the four bases of spiritual power consisting in concentration due to :
1. zeal…
2. energy…
3. purity of mind…
4. concentration…
5. enthusiasm…
… and determined striving.
One who thus possesses the fifteen factors is capable of attaining the supreme security from bondage (anuttara yogakkhema) / arahantship.
