Akshaya Tritiya, which is also known as Akha Teej, is celebrated on Vaishakh Shukla Tritiya (the third Hindu date of the bright half of the Hindu month Vaishakh). It is a major festival for the people of Sanatana Dharma.
On this day, donations, holy bath, Yajna, Japa, etc. give tremendous results. Akshaya Tritiya is a Sanskrit term. Akshaya means something which cannot be destroyed and Tritiya is the third date in the Hindu month.
As per the Puranas, Yudhishthir had expressed it to Lord Krishna that he wants to know the significance of the Akshay Tritya. Hence, Krishna told him that it is a very auspicious day. On this day, those who bathe before the midday and perform Japa, Tapa, Homa, Yajna, study of scriptures, Pitru-Tarpan, donations, etc. receive tremendous auspicious results.
In ancient times, there was a poor and virtuous man, who had faith in the Gods. Being poverty-stricken, he used to stay very disturbed. Somebody suggested him about Akshya Tritiya Vrat. Hence, he performed this fast very ritualistically like waking up early in the morning, bathing in Ganga river, worshipping the Gods, and giving donations.This man became the King of Kushavati in next birth. Thanks to the effects of those Atchaya Tritiyarituals, he became quite mighty and rich.
