A most auspicious day according to the Hindu calendar. Lord Vishnu and Lord Kuber endow great wealth and prosperity on devotees on this day
The word “Akshaya” means imperishable or eternal – that which never diminishes. Initiations made or valuables bought on this day are considered to bring success or good fortune. Buying gold is a popular activity on Akshaya Tritiya, as it is the ultimate symbol of wealth and prosperity. Gold and gold jewelry bought and worn on this day signify never diminishing good fortune. Indians celebrate weddings, begin new business ventures, and even plan long journeys on this day. https://www.thoughtco.com/akshaya-tritiya-1770185
One of my favorite Akshaya Tritiya stories is the Krishna-Sudama Legend where his poor Brahmin childhood friend Sudama came over to his palace to request from him a loan or small grant . As an offering, poor Sudama brought all that he had which was a handful of beaten rice. So, he was actually ashamed to give it to his friend, but Krishna took the rice and happily received it. Krishna was following the practice of ‘Atithi Devo Bhava’ that ‘the guest is like God’ and he therefore treated Sudama like a king. His poor friend was so heartened by the warmth and hospitality shown by Krishna, that he could was too ashamed to ask for the financial favor after all. When Sudama returned to his home, it had been transformed into a palace! He found his family dressed in royal clothing and all of the contents were new and expensive. Sudama knew that it was a boon from Krishna, who blessed him with more than the wealth he actually intended to ask for. Therefore, Akshaya Tritiya is associated with material gains and wealth acquisition. I might also add generosity.
On this day world leaders are to perform Puja at the picture of Vaibhav-Lakshmi for their subjects which should make the subjects happy as well as prosperous. We should remember though to make sure to invoke Lord Vishnu because Goddess Lakshmi is his divine energy (shakti). So to not invite him to our worship on this day will not allow us the maximum benefit of the principle of Lakshmi-tattva”
