It is comforting to sleep with a raga unfolding in the dark*, and thanks to the number of night ragas at hand, things don't get much boring. So I chose Raga Yaman (Kalyani in Carnatic tradition) last night, another of those big, mainstreet Indian classical ragas. I don't have the requisite knowledge to discourse on it, so I will differ to this excellent article by Rajan Parrikar on its musicology, its variants, and not the least, its extensive use in Bollywood music (a quick example: the song Mausam hai aashiquana from good ol' Pakheeza**). Of the many great versions of Raga Yaman that can be had for listening***, I prefer this one by Ustad Amir Khan just because I am in love with his voice. He takes an infinite amount (ok, fifty minutes more like) of time to unfold the raga - this is the way sleep happens with its slow drift of thoughts, and then silence.

* Yes, even though this is not the attitude required to get at the rasa
