Oeff that's a tough question. 'Silat' is a name for 500+ styles ranging from groundfighting systems, pukulan based, pure locking or a mix of various aspects. Muay Thai, as known in the west is pretty much one style, based on a mix of thaiboxing, some aspects of western boxing and karate in it. In thailand there are several variations of Muay Thai though. So it's a comparison between: how does a Honda Acura 3.5 compare to a Ford? What model? What's the size of the engine? etc.
My style (Bukti Negara) is a pukulan based art so it has the same focus on striking as arts like Muay Thai or Boxing (although is even more focussed on just one area of hitting, no kicking)
I'm going to echo taoizt's sentiment on the generic nature of the term "Silat". The type that I practice has some similarity with FMA in the sense that a lot of the empty hand strikes are delivered like a strike with a blade.
pukulan Dude, Just hit hit hit. every three fingers width is a point, so just tenderize. yes lay down 3 fingers width off any joint and on and on just keep hitting and have fun for the love of god
