Tongue that enjoys many forms of sweet and savoury foods, drinks and is relisher of all the tastes is called gustation. Eyes see good and bad, beautiful and ugly and is therefore known as vision power.
Ears for their ability to hear all sorts of sounds, melodies etc. are called hearing power. With the use of all these faculties, one obtains knowledge of various things, focuses one's mind in meaningful thoughts and earns worldly respect.
The skin brings awareness of things through touch. Enjoyment of music and songs, intellect, strength, speech and dependence on discrimination is the boon of the Lord.
But all these senses of knowledge are useful if a person obtains the boon of Guru's wisdom, dwells his mind in the name of the Immortal Lord and sings the sweet paeans of me Lord's name. Such tune and melody of His name is bestower of bliss and happiness.
