第六復次，為治自苦行，建立靜慮支者，謂苦行煩惱能令聖道缺減，名此煩惱為對治缺減，尋伺能治此，故名對治缺減對治也。喜樂為身心逼惱對治，心一境性為於外境流散對治。

In the sixth explanation, regarding the establishment of the factors of dhyāna to counteract one's painful practices: painful practices and afflictions can cause deficiency in the noble path, so these afflictions are called the 'deficiency of the counteractive path'. Investigation and reflection can counteract this, so they are called 'the counteraction to the deficiency of the counteractive path'. Joy and bliss are the counteractions to the affliction of body and mind. One-pointedness of mind is the counteraction to wandering towards external intentional objects.
