What Is Meant by Perfuming the Manas?

When the mind consciousness deliberates on dharmas, it forms its own thoughts, concepts, views, and knowledge-and-views; at the same time, this has a perfuming effect on the manas. The process of deliberation can perfume the manas, and the mind consciousness's focused deliberation can penetrate even more deeply into the mind of the manas, making the effect of perfuming more evident. If it draws the manas's attention and serious regard, that is the most initial effect; if the manas gives rise to alertness and deliberation (manasikāra), the effect is more noticeable; if the manas's deliberation is focused and deep, and is also in accordance with reason and the Dharma, the effect of perfuming becomes even more evident; if the manas's deliberation gains a clear thread, the effect begins to manifest; if the manas deliberates out the flavor of the dharma and makes an initial determination, the real effect emerges; if the manas reaches a very clear and reasonable conclusion, firmly acknowledges what it has deliberated, and makes the corresponding determination and judgment, then the perfuming can be said to have succeeded. Once the manas is transformed, all subsequent mental actions will be transformed, revolving around the manas's judgments and determinations—that is when the perfuming has been fully accomplished.
