अद्य right now, अहम् I, सलिले in waters, आसक्तम् mixed, क्षीरम् milk, निष्पिबन् drinking, सारसः इव like the swan, जीवितान्तकैः that can put an end to life, मार्गणैः by arrows, प्राणान् life, आदास्ये I will put out.
Just as the swan drinks only milk from water (mixed with milk), my arrows will (unerringly) drain the life from the enemy's body right now.
