For my body which is food for dogs and jackals (parakyasya) I have killed many aksauhinis. Vyasa has described the aksauhini.

aksauhini prasamkhyata rathanam dvija-sattamah |
samkhya-ganana-tattva-jnaih sahasrany eka-vimsatih ||
satany upari caivastau tatha bhuyas ca saptatih |
gajanam ca prasamkhyanam etad eva prakirtitam ||
jneyam sata-sahasram tu sahasrani navaiva tu |
naranam api pancasacchatani trini caiva hi ||
panca-sasthi-sahasrani tathasvanam satani ca |
dasottarani sat prahuh samkhya-tattva-vido janah |
etam aksauhinim prahur yathavad iha samkhyaya ||

O best of the brahmanas! Those who understand counting know that an aksauhini consists of 21,870 chariots and the same number of elephants. It has 109,350 foot soldiers. It has 65,610 horses.
