यादेवी सर्वभूतेषु निद्रारूपेण संस्थिता ।

नमस्तस्यै नमस्तस्यै नमस्तस्यै नमोनमः ।।

– Shridurgasaptashati, Adhyaya 5, Shloka 16

Meaning : I pay obeisance thrice to the Devi, who is present in all living beings in the form of nidra.

Keep reciting this shloka. Gradually, the thought process will stop, a rhythm will set in and we will fall asleep in ten to fifteen minutes.
