Namdrol: Buddhist Philosophy and tenet systems is pretty much a dry hump. It does not lead anywhere. In the end it is merely dry intellectualization divorced from personal experience.
It certainly can be 'dry' and 'divorced from personal experience', but it need not be that way. For example, the famous bodhi experience of Je Tsongkhapa came after much pondering on a passage in a Buddhapalita(?) shastra.
This intellectual study can be useful, even essential, when it comes time to teach intellectuals. Then all that mental content can be displayed for their benefit, to keep them attracted to the buddhadharma until a deeper insight is gained.
After all, it seems too goofy to think that Nagarjuna, Chandrakirti, Shantideva et al were wasting their and our time.
