What were the specific steps for the 'Ashtadha-prakriti Puja' that Baba taught the author to perform in order to find the 'eternal treasure'?

The provided text from Chapter 3 does not describe a specific ritual named 'Ashtadha-prakriti Puja.' While Sai Baba did promise that an 'eternal treasure will be found' through devoted service and explained that He pervades the eightfold nature (Ashtadha-prakriti), He did not outline a formal puja. Instead, His instruction was to cultivate a particular state of being. As Chapter 3 clarifies, this involves recognizing His omnipresence in all moving and unmoving things, understanding that the universe is a form of His play, and developing a feeling where 'I' and 'mine' dissolve. This inner realization, not a specific ritual, is presented as the path to the treasure.
