Certain Hindu communities offer Chana Dal and Jaggery to Lord Vishnu. It is considered highly meritorious to make the offering.
It is believed that offering Chana Dal and Jaggery helps in overcoming all forms of financial difficulties. It also helps in overcoming other difficulties.
Chana Dal is slight yellow in color and so is jaggery in some regions. Making yellow color offerings to Lord Vishnu helps in desire fulfillment.
