Worshipping Lord Hanuman is an excellent pariharam for all problems.

Yesterday being Hanuman Jayanti, Hanuman/Rama temples would have been full of devotees.

Let's know some interesting facets of Hanuman:

He is truly a VIP deity-Devotees first pray to Him when they visit Rama temples! Hanuman, the loyal friend of Sri Rama is an Avatara of Lord Rudra-and His power to destroy enemies is well known. Not surprisingly, traditional Indian wrestlers invoke Him (Jai Bajrang Bali) before fighting!

Those who pray to Him get relief from the malefic effects of Shani (The other deity who gives us this protection is Ayyapan), and I have been to a Hanuman temple in Cochin where Poojas are done by the faithful for this. Also known as Anjaneya(the son of Anjana), He is a Chiranjeevi(immortal) and has a very special distinction among all deities-He is present in both the Maha Itihaasas, the Ramayana, and the Mahabharata. Notice the Ratha (chariot) of Arjuna driven by Parthasarathy, you'll find the flag of Hanuman flying high, on top of the chariot.

Hanuman is found in many forms-a peaceful one with hands folded and tail resting on the ground, as the humble devotee of SriRam, a courageous one ready for battle and with the tail upright, etc.One interesting form is the PanchaMukha Anjaneya, with 5 faces, which are for Hanuman, Hayagriva, Garuda, Varaaha and Narasimha.I have seen one temple with Him in this form-this is found 2 km before Marudhamalai in Coimbatore, and is a very good spectacle.
