As per shastras, lighting a diya before 4 plants brings in good luck

In Hinduism, it is not just the Gods and Goddesses that are worshipped, revered, and looked up to, there are also elements of nature, like Agni, Vayu, and even trees that are worshipped. In Hinduism, there is a deep connection between the soul and nature, and thus humans pray to plants and trees just like they do to Gods.
