[147] Dwelling at Sāvatthī. … "Bhikkhus, whatever one intends, whatever one plans, and whatever one has an underlying tendency toward — this becomes a basis (ārammaṇa) for the maintenance of consciousness (viññāṇa). When there is a basis, there is a support for the establishing of consciousness. When that consciousness is established and has come to growth, there is the descent of name-and-form (nāmarūpa). With name-and-form as condition, the six sense bases (saḷāyatana); with the six sense bases as condition, contact (phassa); with contact as condition, feeling (vedanā) … craving (taṇhā) … clinging (upādāna) … existence (bhava) … birth … aging-and-death; sorrow, lamentation, pain, grief, and despair come to be. Such is the origin of this whole mass of suffering (dukkha).
"But, bhikkhus, when one does not intend and does not plan, yet still has an underlying tendency — this becomes a basis for the maintenance of consciousness. When there is a basis, there is a support for the establishing of consciousness. When that consciousness is established and has come to growth, there is the descent of name-and-form. With name-and-form as condition, the six sense bases … Such is the origin of this whole mass of suffering."
