Sound sleep is of great importance. However, many people struggle with disturbed sleep in the night. There are two solutions given by Srimajjagadguru Shankaracharya Svami Sri Nischalananda Sarasvatiji Maharaja,Shankaracharya of Puri (referred to as Maharajaji), to address this problem.
Mantra to Chant –
Maharajaji shares an example of a sant from Vrindavan. The sant suffered from lack of sleep for forty long days. This put him in great agony and he cried out aloud. The people of his ashram used to throw him out at night since his crying disturbed everyone else too. At that time Maharajajiwas a dandi svami. Someone brought the sant to him, in order to get help and resolve this distressful situation.
Mahārājajī asked him to chant the below mantra –
या देवी सर्वभूतेषु निद्ररूपेण संस्थिता।
नमस्तस्यै नमस्तस्यै नमस्तस्यै नमो नमः॥
Ya devi sarvabhuteshu, Nidra rupena samsthita I
Namastastyai Namastastyai Namastastyai namo namaha II
(from the Tantrokta Devi Suktam)
The sant found it very hard to comprehend the mantra so Maharajaji translated it and gave it to him in an abbreviated form. After starting the practice of chanting the mantra, the sant started getting eight hours of deep and sound sleep.
Change your attitude –
Do not think of yourself as your own master or the master of your home. Instead think of Bhagavan as the master and consider yourself only to be the manager of your life and household. Do not take unnecessary responsibilities. Offer your entire life to him.
Chanting the mantra and changing your attitude will help you get deep undisturbed sleep.
