Om Sai Ram.
Please chant 'Sai Sai Sai' when you feel scared or anxious. Chant Baba's name with love and devotion, and as much as you can. It helps calm our nerves and brings us Baba's blessings. Seek His grace sincerely, and accept whatever He decides for your life. Trust Him even if the result is contrary to your expectations. Believe that whatever He gives you will be in your best interest in the long run. Passing and failing an exam does not matter as long as Baba remains in control of our lives. I failed a very important exam once, and cried a lot for days together. But, looking back, I think that was the best decision that Baba made for me. If you entrust your life to Him, be prepared to accept the bitter pills that Baba may administer sometime . You are in absolutely safe hands. Please have no doubts about that.
Om Sai Ram.
