The first deity that we worship is the Goddess Dharti Maa, Prithivi Mata or Bhumi Ammaa.
Dharti Maa, often referred to as Bhumi Ammaa, Pritivi Ammaa or Mother Earth is the giver of food, shelter and many other essentials necessary to sustain life on Earth. She nourishes our land with fertility and fruitful crops.
She blesses us with all materials necessary to perform Mariamman poosai. Therefore, we first pay our respects to the Divine Mother Earth who carries us on her lap.
