Contemplation versus meditation Is there an obvious or well-understood difference between "contemplation" and "meditation"?

I'm reading a book -- modern, probably Tibetan-language originally, translated into English -- talking about the "lack of fixation" and "realization of the nature of the mind". It says that all the Buddhas have taught this and,


  There are two ways we can come to know it: through study and inference or by knowing it directly. The way we need to know it is through direct yogic experience in meditation. We need to develop the discernment that knows this. This discernment is not the intelligence of either listening or contemplation; it is the intelligence of meditation.


I don't know how to distinguish "contemplation" from "meditation" -- or "direct yogic experience" as opposed to an[y] other mental experience or phenomenon.
One way I've seen this difference defined was in a text about Dzogchen "meditation of non-meditation". They said that traditional meditation involves conditioning or shaping the mind, while contemplation involves watching without trying to manipulate. Dzogchen non-meditation was characterized as a type of contemplation, rather than regular meditation. Incidentally, the Zen meditation I was taught (a Korean type of Shikantaza) had also emphasized this non-manipulative aspect.

I don't think this is what "contemplation" means in your text though. It seems like when they refer to "contemplation" they mean "mulling over" as opposed to "seeing" directly. So it seems your book is making the same point as my sources ("just watch what's here") while confusingly using the opposite words to convey it.
