Usually Shanivar or Saturday is dedicated to Hanuman Puja and in Shravan month Lord Hanuman is also worshipped along with Lord Shiva because he is also known as Rudravar (incarnation of Lord Shiva). Along with Hanuman Ashwatha Vriksh (Banyan tree) is also worshipped on Saturdays in Sravan mahina.
Ashwath Vriksh is considered as the ‘sarva devata vriksh’, where all the Gods live. Ashwatha Vriksha Stotra defines the above in detail. It is believed that in the roots of Ashwath Lord Brahma lives, in the stem of the tree Lord Vishnu lives, and on the peak of the tree Lord Shiva lives. This is the reason why Ashwath vriksh is also offered prayers in Sravan month.
