Om Sai Shri Sai Jaya Jaya Sai

"I resorted to My Guru for 12 years.  He brought Me up.  There was no dearth of food and clothing.  He was full of love or say, he was love incarnate.  How can I describe it?  He loved Me most.  Rare is a Guru like him.  When I looked at him, he seemed as if he was in deep meditation, and then we both were filled with Bliss.  Night, and day, I gazed at him with no thought of hunger and thirst.  Without him, I felt restless.  I had no other subject to meditate, nor any other thing than My Guru to attend.  He was My sole refuge.  My mind was always fixed on him.  This is one pice of Dakshina, Saburi (Patience or perseverance) is the other pice.  I waited patiently and very long on My Guru and served him.  This Saburi will ferry you across the sea of this mundane existence.  Saburi is manliness in man, it removes all sins and afflictions, gets rid of calamities in various ways, and casts aside all fear, and ultimately gives you success.  Saburi is the mine of virtues, consort of good thought.  Nishtha (Faith) and Saburi (Patience) are like twin sisters, loving each other very intimately."

Bow to Shri Sai - Peace be to all
