The Vayu Linga in Srikalahasthi and deekshithar’s krithi on Kalihastheeswara.
Kalahasthi temple is situated 36 km from the temple town of Thirupathi. This temple is usually referred top as Dakshina Kailasam. This temple has been named after a spider(sri) , serpent(Kala) and an elephant (Hasthi) who were very great devotees of the Lord.It seems once upon a time the elephant used to daily do Abhishekam by bringing water in its trunk and later worship the Linga by BIlwa leaves.It seems the spider was protecting the Linga by spinning a web and the serpent was guarding the linga and used to place the SArpa rathna(Gem of serpent) on the top of the LInga for decoration.
It seems once Goddess Parvathi was cursed by Lord Shiva to take a human form and she did penance here to get normal divine form. It seems Lord Shiva was pleased by her great penance and gave back her divine body and also taught her divine wisdom.Because of this the Goddess at this temple is called Jnanaprasoonambika .There is also another story of this temple associating it with a hunter king Kannappa. It seems this hunter was daily worshipping the linga .One day he saw blood flowing from one of the eyes of Linga.Greatly perturbed he plucked one of his own eye and replaced that wounded eye . But then blood started flowing from the other eye. Greatly shocked , it seems he plucked another of his eyes and replaced the other eye .God was pleased personally came there and granted him salvation.
The lamp I lit in the sanctum of the temple , which does not have any windows it seems keeps on waving proving the existence of wind in the sanctum sanctorum. This is the reason why people believe that God here is the Vayu Linga. This temple is also a pariharasthala for sarpa dosha. It is believed that if this parihara pooja is done in the Rahu Kala it is extremely effective.
This temple also has sub temples for Shiva Lingas dedicated to all the five elements.
Muthuswami Deekshithar one of the musical trinity of Tamilnadu had visited this temple and has composed a Krithi extolling the Lord and the Goddess.. Here is that Krithi with English translation:-
Sri Kalahatheesa sritajanavanasameerakara,
Maam pahi Rajamaule ehi
Please protect me oh God of Kalahasthi , who protects those who take refuge in you,
Who is the form of air and who is Rajamauli
Pakari vidhi hari pranamaya kosa anila aksha
Bhumi salilagni praksha shiva,
You are the soul of Indra, Brahma and Lord Vishnu
And you are the air who illuminates the ether , earth , water and fire,
Jnana prasomnnambika pathe , bhakthabhimana ,
Dakshina Kailasa vasa, abheeshta dana chathura karabja,
Deena Karuna nidhe soona shara suda, ajnana hara pasupathe ,
(Madhyama kala sahithyam)
Jnana Guruguha sachidanandamaya murthe,
Hina jathi kiratakena poojitha keerthe
Lord of Jnanaprasoonambika who lives in Dakshina Kailasa,
Recognised by devotees , who fulfills desires ,
Who using his able lotus like hands is the treasure of mercy of the suffering,
Who killed God who has arrows of flower , who destroys ignorance , Who is lord of all beings ,
Who was taught Jnana by Subrahmanya , who is pervaded with divine joy
And who has the fame of being worshipped by a lower caste hunter.
