I will be posting the most beautiful parts of the Devi Mahatmyam (Glorification of the Goddess, also known as Durga Saptashati, and as Chandi), which are generally hymns and prayers. I'll begin it now, at Chapter I, verse 73:

त्वं स्वाहा त्वं स्वधा त्वं हि वषत्कारः स्वरात्मिका
सुधा त्वमक्षरे नित्ये त्रिधामात्रात्मिका स्थिता ||73||

tvaM svAhA tvaM svadhA tvaM hi vaShatkAraH svarAtmikA
sudhA tvamakSharE nityE tridhAmAtrAtmikA sthitA ||73||

You are svaha (propitiatory mantra) and svadha (propitiatory mantra for ancestors),
You are verily the vashat-kara (vedic sacrifice) and the embodiment of svara (the heaven to be attained)
You are the nectar (of immortality), oh eternal and imperishable one,
You are the embodiment of the threefold matra (the OM sound).


Devi Mahatmyam (Glorification of the Goddess) I.75:

त्वयैतद्धार्यते विश्वं त्वयैतत्सृज्यते जगत्

tvayaitaddhAryatE vishvaM tvayaitatsRRijyatE jagat
tvayaitatpAlyatE dEvi tvamatsyantE cha sarvadA ||75||

By you this universe is borne,
By you this universe is created,
By you it is protected, oh Devi,
And you always consume it at the end.

You are Savitri (the Savitri hymn in the Rig Veda) and
The supreme Mother of the devas.

Oh you who are of the form of the whole world, at the time of creation
You are of the form of the creative force, at the time of sustaining
You are of the form of the protective power, and at the time of the dissolution
Of the world, you are of the form of the destructive power.
