Before observing the Solah Somwar Vrat, it is important to keep three key things in mind. First, maintain purity in thoughts, words, and actions throughout the vrat period, as this fast is dedicated to Lord Shiva and requires spiritual discipline. Second, follow a sattvic (pure) diet and avoid negative habits like anger or dishonesty. Third, understand the vrat's purpose—seek Lord Shiva’s blessings with sincere devotion, not just for material gains. Performing the vrat with true faith and regular prayers brings peace, marital harmony, and spiritual upliftment in life.
