Addressing this doubt, in order to explain the mind, it is…

““Addressing this doubt, in order to explain the mind, it is taught: || citir eva cetana-padād avarūḍhā cetya-saṅkocinī cittam || 5 || Awareness (citi) itself, descending from its state of pure consciousness (cetana), becomes contracted by the object perceived: this is [called] the mind (citta). Far from teaching an absolute distinction of divine spirit and mundane matter, Tantra teaches that they are in fact different phases of one thing, i.e., Awareness. Take the example of h2o: in one phase, we call it steam, in another, water, in another, ice. These three states are very different from one another, and we necessarily interact with each of them in very different ways. This is a perfect analogy for what Kṣemarāja intends here: there are three different states or phases of one ‘thing’—in one state, we call it God, in another, pure consciousness, in another, the mind. The implications of this are of course huge. First, though, let’s explore the specific three terms that Kṣemarāja is using here for these three states of the One. First we have citi, introduced in the first sūtra, which we translate (imperfectly) as Awareness. Citi (pronounced CHIT-ee) is the state in which Awareness is fully expanded, that is to say, untouched by any trace of contraction, including that of subjectivity or selfhood. In other words, there is no concealment whatsoever operative on the citi level (not that it’s really a level, of course). When citi manifests as an individuated subject, then that is the phase called cetana, here translated as ‘pure consciousness’. We have to define this second phase, cetana, more carefully so that we don’t confuse it with the third phase (the mind). Cetana (CHAY-tuh-nuh) is the state of being the conscious knower or agent of consciousness. We experience cetana in the space between trains of thought, a space of awareness momentarily devoid of thought-forms (vikalpas). That’s why I translate it as ‘pure consciousness’. We experience it dozens of times a day, but usually only for a second, and usually without the reflective self-awareness (vimarśa) by which we can know that we are experiencing cetana. (This ‘knowing’, when it does occur, does not take the form of a thought, or else it is no longer the cetana state.) The cetana state is open and expansive awareness; in fact, it is as expanded as awareness can be while still having a subtle ‘sense of self’.””
