God needs a Hirda to appear in as He is not born and never dies. The closest the Creator comes into the creation is by appearing in the Hirda that has become Sat. That is why God appears in the Hirda within the physical body of a Puran Sant Puran Braham Gyani, a SatGur, a Puran Khalsa. Please remove the incorrect phrase Dehdhari Guru from your mind and the incorrect preaching that is associated with it to prevent people from seeking out a Sant. Deh is never the Guru, but the Sat in the Hirda is the Guru.
SatGur Pancham Patshah Ji is very kindly giving us the divine wisdom to follow these souls. The Sangat of such souls is called Sat Sangat. In their Sat Sangat we become a Sat Roop. Our Hirda becomes a Sat Hirda. Our Hirda becomes a Sant Hirda. Following these souls means complete surrender with Tunn, Munn and Dhann at their Charans with complete trust, faith, devotion and love. By doing so, we pave a path for our self to Jivan Mukti. The ones who do so achieve Jivan Mukti. Therefore, please open up the closed minds and use your common sense to follow the Shabad Guru and not just what is being preached by those who are not even authorized by God. Just do what GurBani is telling you to do and realize the unimaginable benefits. Just do it and see what happens inside you. We promise you that when you do GurBani in your daily life you will for sure become whatever GurBani says. To be more explicit you will become the Mahima of Akal Purakh.
