Talk to my right ear!

During Upanayana Samskara (ceremony of administering the sacred thread to the young boy), the father of the boy performs the ‘Brahmopadesha’ by chanting the Mantra to the right ear of the boy.
If one gives up his life in Kashi (Varanasi), it is said that Lord Vishwanath liberates the soul by chanting the ‘Rama’ Nama in the right ear of the ‘Jiva’.
Why is it ‘right ear’ always?
Today, scientists have proved that the right ear is more sensitive to verbal stimulus.
While numerous studies have been performed on the left and right brain-hemispheres, recent findings are startling.
In three separate real-time scientific studies conducted in Italy, researchers have found that the response was far better when the stimulus was provided to the right ear of the individual, especially in chaotic social environments.
