In its original, atheist Carvaka writings contained much verse (as Indian philosophy/theology usually does); see http://www.humanistictexts.org/Carvaka.htm In translation, they almost sound like senryū:
If a beast slain as an offering to the dead
will itself go to heaven,
why does the sacrificer not straightway offer his father?
Reminds me of the doctrine that some Christians have, where anybody who dies before a certain age automatically goes to heaven, while people above that age can go to hell. The question then becomes: why don't parents kill their children, thus saving them from the all-too-likely possibility of eternal torture?
(Fun fact: most people who believe in hell can be made very uncomfortable if you look at the unfortunate implications of what they believe.)
