Lakshmana’s sleep

As per notions, beliefs and stories prevalent about Lakshmana, he did not sleep for 14 years, serving Sri Rama.  It is also prevalent that Indrajit had a boon that a person, who will not sleep for 14 years, can only slay him. 

------

According to Srimad Valmiki Ramayana neither Indrajit received such a boon nor did Lakshmana serve Sri Rama without sleeping.  

The following narrations in Slokas 1 to 3 of Sarga 56 of Ayodhya Kanda did confirm that Lakshmana slept during his stay in forest.

अथ रात्र्याम् व्यतीतायाम् अवसुप्तम् अनन्तरम् |
प्रबोधयाम् आस शनैः लक्ष्मणम् रघु नन्दनः ||

"Then, Sri Rama gently woke up Lakshmana, who was sleeping without break, even when the night was passing away."

सौमित्रे शृणु वन्यानाम् वल्गु व्याहरताम् स्वनम् |
सम्प्रतिष्ठामहे कालः प्रस्थानस्य परम् तप ||

 

"Oh, Lakshmana! Hear the sound of wild animals, resounding beautifully. It is time for our journey. Let us start."

स सुप्तः समये भ्रात्रा लक्ष्मणः प्रतिबोधितः |
जहौ निद्राम् च तन्द्रीम् च प्रसक्तम् च पथि श्रमम् ||

 

"Lakshmana, who was sleeping, being woken up by his brother at the right moment, had relinquished sleep, sloth and strain, which resulted on the way."

There is a difference between being alert while in forest and not sleeping.  

Lakshmana was alert during his stay in forests.
