Goddess Tripura Bhairavi (the sixth Mahavidya) is worshipped, especially on the sixth day, for prosperity, success in career, wish fulfilment (like marriage), and destruction of sins, with worship involving chanting mantras, Kavach, Yantra, and Stotras, often with Tantric focus, bringing blessings like good fortune, health, and powerful attraction. ‘Chadhawa’ typically refers to offerings, and ‘Sewa’ to devotional service, often involving prayers, rituals, and offerings (like sesame oil lamp) to invoke her transformative, Kundalini energy for spiritual and material growth.
