आत्मनः my own, राज्यम् kingdom, प्रार्थयता by desiring, सुग्रीवेण by Sugriva, नृशंसेन by the wicked one, अनेन by him, भ्रातृसौहृदम् brotherly love, विस्मृत्य forgetting, अहम् I, तत्र there, अस्मि I am, संरुध्दः I was obstructed
'I was obstructed by wicked Sugriva who forgot his brotherly love and was desiring the kingdom, which belongs to me.'
