Shelter of the holy feet of God-Guru.  As a result of our complete surrender at the Charan Sharan of our Guru, when we are blessed with the GurParsaad of Naam, Naam Simran, Naam Ki Kamai, Puran Bandgi and Seva – Parupkaar and Maha Parupkaar.  This is Puran Bandgi.  Now as Naam goes into our mind and surat, we experience a unique peace inside our mind.  We feel a strange kind of soothing happiness inside our Hirda and our whole being enters  wonderful eternal bliss.  This kind of GurParsaad is achieved only from a Puran Sant Puran Braham Gyani, a SatGur or a Puran Khalsa. 
As soon as we surrender at the Charan Sharan of such a soul, we are accepted under the Chattar of such a soul.  Once we go under the Chattar of such a soul, we are showered with Amrit.  There is no effect of Maya under such a divine Chattar and there is a continuous shower of Amrit that we are able to enjoy. 

When we go under the Chattar of such a soul then we are in the Sat Sangat on a continuous basis.  That means regardless of whether we are physically in front of such a soul or even if we are sitting thousands miles away, we are still sitting under the Chattar of such a soul.  So Maya is unable to touch us if our trust, devotion and love is infinite.
Sitting under the Chattar of our Guru means that we are sitting inside the Hirda of our Guru.  So where is the question of Maya attacking us when we are sitting in a Sat Hirda?  At the same time those who don’t surrender completely at the Sat Charans of their Guru will continue to see attacks of Maya according to their trust, devotion and love for their Guru and how much they give to their Guru in terms of Tunn, Munn and Dhann.  This is the reason why those who have not been blessed with Puran Bandgi, because of their partial surrender to their Guru, they keep on seeing the attacks of Maya now and then.
