I'm reading this technical, hardcore meditation manual book
'Mahamudra: The Moonlight' by 16th century Mahamudra Master Dakpo
Tashi Namgyal.
As I said, this is much more technical, hardcore, kind of dharma
book coming from someone with very deep insight and experience,
elaborating the topic of meditation with amazing depth and
clarity.
Highly recommended reading.
Oh and I guess you could start with 'Clarifying the Natural
State' first because it is easier and shorter to read. Then get to
this one. Commentaries by Thrangu Rinpoche for both texts are also
highly useful and well written.

" Emaho! In this book Dakpo presents the most clear and detailed
exposition on Mahamudra practice that I've ever seen. Every step of
the practice is very thoroughly discussed ---- proper method,
common problems and their remedies, common misinterpretations, etc.
The translation is very clear. Best of all, whenever he explains
something or offers a useful method to overcome a hangup, he cites
the source! This 500 year old book just might meet APA standards
^_^. It reads like a technical manual, and appeals very much to my
intellectual mind. For me, this detailed exegesis works to develop
faith in the practice and the lineage by exhaustively answering
every question my doubtful mind raises. This might be all you need
for a lifetime of practice (although I would throw in his
Clarifying the Natural State for good measure). If you are a
Mahamudra practitioner (particularly in the Kagyu lineage) get this
book. Even if you are not and you simply want the most detailed
explanation of shamata (samatha, shamada, shinay, zhine) and
vipassyana (vipassana, lhak thong, lak tong) around, then this book
is for you!"
