Answer in Details
Sin (pāpa) is not an obstacle that cannot be overcome. Lord Shiva is known as Ashutosh—the easily pleased—and is the destroyer of sins. Through sincere repentance, chanting of Shiva’s names (such as “Om Namah Shivaya”), and maintaining truth (sathya) in your actions, you can purify your mind and karma.
Start with small acts of worship: light a lamp before a Shiva lingam or image, offer water or bilva leaves, and sit in quiet meditation, chanting “Om Namah Shivaya.” Ask Lord Shiva to guide you, and trust that when the time is right, the Guru will appear—either externally or as inner wisdom.
Remember, Lord Shiva teaches patience, surrender, and perseverance. Do not lose heart. The path will clear as your devotion deepens.
