Hanuman Jayanti is Hanumanji's birthday and falls on Chaitra Shukla Purnima (the March-April full moon day). On this holy day worship Sri Hanuman. Fast on this day. Read the Hanuman Chalisa. Spend the whole day in the Japa of Ram-Nam. Sri Hanuman will be highly pleased and will bless you with success in all your undertakings.
Sri Hanuman is worshipped all over India-either alone or together with Sri Rama. Every temple of Sri Rama has the murti or idol of Sri Hanuman. Hanuman is the Avatara of Lord Shiva. He was born of the Wind-God and Anjani Devi. His other names are Pavanasuta, Marutsuta, Pavankumar, Bajrangabali and Mahavira.
He is the living embodiment of Ram-Nam. He was an ideal selfless worker, a true Karma Yogi who worked desirelessly and dynamically. He was a great devotee and an exceptional Brahmachari or celibate. He served Sri Rama with pure love and devotion, without expecting any fruit in return. He lived to serve Sri Rama.
