พระอาจารย์อธิบายคำว่าเจตสิกผ่านอุปมานักแสดง จิตคือผู้รู้บทและภูมิหลังของตัวละคร ส่วนเจตสิกคือความรู้สึกที่นักแสดงต้องถ่ายทอดออกมาขณะแสดง ชีวิตเราก็ดำเนินไปตามจิตและเจตสิกสองอย่างนี้The teacher explains cetasika through the analogy of an actor: consciousness (citta) is the knower of the script and the character's background, while cetasika is the feeling the actor must convey while performing. Our lives unfold according to exactly these two things.
One student explained that listening to the teacher use the word "" over and over, it feels like understanding starts to form — but when asked directly what cetasika actually means, no clear answer comes. He asked the teacher to explain it again.
The Actor Analogy: Consciousness Is the Script, Cetasika Is the Feeling Conveyed
The teacher explained it through the analogy of an actor. Picture an actor about to play a role — say, a recent graduate heading into a job interview, from a middle-class family background, and so on. The actor must study the script to understand who this character is and what their background is; this part is "citta" (consciousness), the knower of the role, aware of the overall situation being portrayed. Once the actor knows the script, they must step into the scene — say, the interview scene itself. Beyond simply saying the lines, what separates a skilled actor from an unskilled one is the feeling conveyed while performing. That feeling which must come through is exactly what's called "cetasika" — the emotional quality of the mind in that moment. Speaking the lines according to the script belongs to citta, directed as though by an unseen director behind the scenes. Our life unfolds according to exactly these two things, citta and cetasika: something directs us to say this or that, and an emotional quality must be conveyed alongside it — that emotional quality is cetasika.
