Ji says: A name expresses a dharma's name itself, its substance being coarse; the mental investigation can contemplate all dharmas resembling nominal expressions, hence it is called 'having the nature of mental speech'. Furthermore, spoken names are verbal names, while reflective thought is called mental names; because investigation is mental naming, it is called 'mental speech'. In the Hīnayāna, investigation and reflection are associated with the fundamental [dhyāna]. Someone says: Now in the Mahāyāna it is not so; investigation and reflection are only in the preparatory stages. This is not so; elsewhere it also says that in concentration there is no investigation or reflection, meaning there is no investigation and reflection that initiates speech, not that there is no subtle investigation and reflection; moreover, there is no fundamental dhyāna lacking five factors, for it is established as a factor.
