ghātayiṣye - I shall have Them killed; iha - here; ānītau - brought; kāla-kalpena - like death itself; hastinā - by the elephant; yadi - if; muktau - They go free; tataḥ - then; mallaiḥ - by wrestlers; ghātaye - I will have killed; vaidyuta - lightning; upamaiḥ - just like.

After you bring Kṛṣṇa and Balarāma, I will have Them killed by my elephant, who is as powerful as death itself. And if by chance They escape from him, I will have Them killed by my wrestlers, who are as strong as lightning.
