एतत्ते बलसर्वस्वं दर्शितं राक्षसाधम।
शक्तिहीनतरो मत्तो वृथा त्वमवगर्जसि॥

etat = here; te bala-sarvasvam = the entirety of your strength; darśitam = you have exhibited; rākṣasa-adhama = O worst of the rākṣasas; śakti-hīnataraḥ mattaḥ = [though] you are inferior to Me in strength; vṛthā = in vain; tvam = you; avagarjasi = brag.
O worst of the rākṣasas, you have exhibited the entirety of your strength here. You brag in vain [though] you are inferior to Me in strength.
