आत्मन् = self मुख = mouth दोष = fault शुक = parrot सारिका = a bird (nightingale / cuckoo ? ) बक = stork बध् = to trap, to tie down. मौन = silence सर्व = all अर्थ = objective साधन = instrument भावार्थ Nightingales and parrots are trapped because of the fault of their own mouths. However, storks are not caught. Silence is indeed the instrument that achieves all ends.
