110. *pazhuthE palapagalum pOyinavenRu* izhantha nALaikkuk kUppidukiRavanukku uRanga viragillai.
For one who worries about all the time wasted in the past without enjoying Him, as per Poygazi Azhvar's "pazhuthE palapagalum pOyinavenRu", there is no further time left for sleep.
Sri PBA Swami's Sarartha Deepikai:
There is also another reason for not having sleep.
As told by Poygai Azhvar (First Thiruvanthathi 16), "pazhuthE palapagalum pOyinavenRu anjiyazhuthEn", the soul that has developed the taste to reach Him, will cry and worry that he has wasted all this time without enjoying Him. For such a person, from this time on, there is not even a moment left to sleep.
