This stotram is dedicated to Goddess Parvati and is part of Durga Saptashati. When we offer our prayers to the Goddess, we can make mistakes in the vidhi (method), therefore this prayer is sung at the end to ask for forgiveness for our prayers that may lack in some way.
दासोऽयमिति मां मत्वा क्षमस्व परमेश्वरि॥१॥
as your slave, Oh great Goddess please forgive me.
पूजां चैव न जानामि क्षम्यतां परमेश्वरि॥२॥
I also do not know how to worship you, Oh great Goddess, please forgive me.
यत्पूजितं मया देवि परिपूर्णं तदस्तु मे॥३॥
And so whatever worship I do, please make it complete.
यां गतिं समवाप्नोति न तां ब्रह्मादयः सुराः॥४॥
Still you look after his salvation, and this cannot be done by Brahma and other Devas.
इदानीमनुकम्प्योऽहं यथेच्छसि तथा कुरू॥५॥
Please decide on the fate of this shivering one according to your wishes.
तत्सर्वं क्षम्यतां देवि प्रसीद परमेश्वरि॥६॥
And so excuse them all and be pleased with me.
गृहाणार्चामिमां प्रीत्या प्रसीद परमेश्वरि॥७॥
Please accept my worship and with love become pleased with me.
सिद्धिर्भवतु मे देवि त्वत्प्रसादात्सुरेश्वरि॥८॥
And make me powerful, through your grace, Oh Goddess of the Devas.
