It's a celebration of Holika Rakshas dhahan. It mean if any negativity in our inside we vanish that. Like a fire vanish all what we give that will be ash. N Another one concept/reason also is there. That is unity. This day we celebrate with each other who we don't know we spread colors of them. No age bondage, no caste, religion, nothing comes under here.
We share happiness in this festival.
Happy Holi with colorful life. - Dr. NETHRAVATHI VALEE . Astrologer
