What is the spiritual benefit of doing Pind Daan at Gaya?

According to Garuda Purana and various Smriti texts:

• It grants moksha to souls trapped in lower realms
• It may remove Pitru Dosh from family charts
• It leads to ancestral blessings for health, progeny, and peace
• It fulfills one’s duty toward ancestors (Pitru Yajna)
• It clears obstacles in career, marriage, and childbirth believed to be due to ancestral dissatisfaction Gaya is where Lord Vishnu Himself blesses the souls, making it unparalleled for such karmas.
