if you let the emotional burst point to continue there, it will inevitably become automation to the point where your painbody completely take over your logical or peaceful mind, and hence you witness an emotional trigger by random people on public venue

Your ego will be your second enemy
that's your false self telling you,
you're not good enough
somebody else has better house or earn more money than you etc

and if you let it automatically dictate how you see the world, you will forever become a slave to the impermanent matters of this world
