such [cruel] kāl̤iya-s —

one who is donning the resounding anklet on his divine foot —

that is like death; —

 being antharyāmi (inside resident) to the five core elements  the big earth, air, fire, water, space, —

rising against his divine feet —

time will become weak and perish —

 in the krutha yugam when having many forms, and took nectar from the divine milky ocean —

death —

the end time —

other than the one who is having a magnanimous form resembling a dark cloud —

and created great dark clouds —

instead, if you call them —

during the time when they announce victoriously like a war cry —

when there was no scope to know about such relationship —

 having six feet —

for the times when we have no means (help) —

and discus on one foot —

being the controller of the wheel of time (to ensure that the apt time for the surrendered ones be at his disposal, having the units such as month, season, year etc) —

Lord Rama used His bow —

that prevail in air —
