Mastergaru's emphasized the importance of reading Sri Guru Charitra along with Sri Sai Leelamritam (Sai Baba the Master) everyday for true followers of Sri Shirdi Sai Baba. Read the introductions to both these books for his elucidation.
Babugaru (Sri Ekkirala Dwarakanath Jnaneswar) started Krutgnayata Archana (Worship with Gratitude) to this holy book itself in the spirit of Mastergaru's teaching a few years ago at Nagole. This year too on the first sunday of September, sharp at 10:00 am the puja was performed at Sri Datta Sai Manga Bharadwaja Nilayam, Nagole and worldwide.
This is similar to how devotees revere The holy Guru Granth Sahib and the the holy Koran as the very embodiment of the Prophet. The same tradition is mentioned in the Bible. Some quotes below:
Therefore everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock.Matthew 7:24
For the word of God is alive and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.Hebrews 4:12
Heaven and earth will pass away, but my words will never pass away.Matthew 24:35
Jesus answered, “It is written: ‘Man shall not live on bread alone, but on every word that comes from the mouth of God.’”Matthew 4:4
Do not merely listen to the word, and so deceive yourselves. Do what it says.James 1:22
