Rujubaluka is the sacred spot where Bhagwan Shri Mahavir Prabhu achieved "Kevalgyan". According to Shwetambar scriptures, Lord Mahavir attained "Kevalgyan" during the later part of the auspicious `Vijay Muhurta` on the 10th day of the bright half of Vaishakh Shukla in the year 511 before the Vikram Era (557 B.C.). This took place under a Shal tree in the farm of a peasant named Shyamaka on the bank of the river Rujubaluka near the small old Vyavrutta shrine on the outer skirts of the village called `Jambhiya`. Every particle of this place is purified and sanctified by 12 years long severe penance and attainment of omniscience of Bhagwan Mahavir Swami, the 24th Tirthankara.
Etymology of Rujubaluka
Present Barakar River was named `Rujubaluka` in ancient times. The word "Rujubaluka" comes from the word `Ruju` meaning Soft and `Baluka` meaning Sand. Thus it is said that the name of this river has been termed for its soft sand.
Historical Evidence of Rujubaluka
On account of Lord Mahavir`s 12 years` intense penance and his attaining "Kevalgyan", this place has become holy. During 16th Vikram Century Sri Hansa Soma Vijayji, during 17th Vikram century Sri Vijay Sagar Vijayji and Sri Jay Vijayji have in their respective Tirthmalas given full description of this place. In them there is no difference of opinion about the name of villages, rivers etc.
From various stone inscriptions, it is found that the last major repair work was carried out here during Vikram Samvat 1930.
Present Evidence of Rujubaluka
Today there is a village named `Janaka` which is about 4 kms from this spot. Also a forest full of Shal tree is found there. Ancient name of Janaka is `Jambhiya`. According to one opinion widely held, another village called `Jamui` which is 56 kms from Rajgiri is Jambhiya and the river nearby which is known as `Kwil` is really Rujubaluka but there is no definite evidence available in this regard.
The scene of the temple situated on the bank of the river is very pleasing. The artisanship also is impressive. In this river an ancient idol of Lord Mahavir of exquisite beauty was found and this idol is at present installed in the temple. There is no other temple nearby.
