Palash Wood is used for havana and Yagna. The mantra to overcome obstacles due to afflicted Moon is “Om Shram Shreem Shroma Saha Chandramase Namah”
Chandra rides his chariot (the moon) across the sky every night, pulled by ten white horses or an antelope. He is connected with dew, and as such, is one of the gods of fertility. He is also called Nishadipati (Nisha=night; Adipathi=Lord) and Kshuparaka (one who illuminates the night). He as Soma presides over Somvar or Monday.
