In search of the true self Siddhartha reached village of Sena in the Uruvela region. Near the banks of river Niranjana he found five monks who were practicing hard meditation. In the dense forest of Uruvela the monks were performing austerities. Siddhartha was amazed to see their mind control and breathing practices. They were leading a very disciplined life living on barely nothing and making their body suffer the hardships to attain various powers.
Siddhartha too joined them and trained himself in the hard rituals and practices. He meditated on austerities and gave intense pain to his body. For six long years Buddha kept practicing the hard training. Demon Mara came to know of Buddha's advancement in search of truth. He came to Buddha and coaxed him to leave his meditation .He warned him that he would die of hunger and he should go back to his Kingdom.
