Yes, the bushi (and the Samurai as their elite wariors) where just head hunters for some times, but the wokd has htransformed in such good way from those times, and the way of the sword (kendo in Japanese) have somehow included the meditation and it's pretty good (I have been practicing kendo for 22 years na I'll be practincg it further).
Nobody asks you to meditate or to practice kendo but both of them really helps, and the world may be changing again in the following years if the Russians or the Chinese are starting the third world war so you may need both of them in real life. We'll live and see if that's the case or it it's just a mad & bad idea (I hope for the last part).
