Although the mechanistic Darwinian puts it all down to superstition & traits of evolution, a common thread in various cultures throughout the world of the  worship of various Demigods and Goddesses cannot be ignored, Siva , Durga , Sarasvati etc etc  are worshiped   , but sometimes under different names  and in different ways in different cultures .

The purpose of the worship of Demigods and Goddesses is to seek various benedictions , by doing so one learns to respect higher beings of all sorts,  gets varieties of benedictions and a greater understanding of respect and sacrifice  is brought to bare . Ultimately this leads to the  benefits of  gradual spiritual evolution of knowledge culminating by good fortune ,  to the  service of  Lord Visnu,  or even more intimate knowledge of Divinity can be understood in the pastimes of spontaneous love with the Supreme Personality of Godhead  Krishna . Ultimately if one can aquire the association of a pure Gaudia vaisnava devotee , one can enter into the association of those that serve Krishna greatest devotee , such is Her alluring nature , that Krishna is forever seeking Her association , and hankering for Her beautiful glances and smiles , with Her eternally blissful and evernew and ever enthusiastic playful form  , Vrsabhanu Nandini Srimati Radharani , is the Supreme Goddess of fortune . Sri Caitanya Mahāprabhu has revealed these truths to the Goswamis of Vrndavana , who have composed many slokas and written extensively revealing to the world , the secret of all secrets .

So why not worship the Supreme Goddess of fortune,  who is only too willing to award Her sincere following the best of what’s in existence in the material and spiritual realms , and as She gives it to you,  it increases.
