With regard to money, Shri Sai Baba demonstrated many a time that it has no value.
One of the many is below: One day, a rich man came to Baba and asked for Brahma Jnanam. He said, that is the only thing lacking in his life and he has got all. Baba said- I am very happy. Rarely, I find someone asking for this, as everyone is coming to me to seek materialistic things.
Saying thus, HE was sending someone to the shopkeepers to lend HIM some money and they all refused to lend Baba Sai any money fearing that they will not get it back. The rich man, who came to seek Brahma Jnana, was seeing all this, but instead of giving that money, kept quite. Finally he said, give me the Brahma Jnana fast, as I have to leave. Then Sri Sai Baba coolly told him - "I am trying the same. However, if you do not give Rs 5 (in this context, his ego, his buddhi etc.. which means surrendering to the HIM), then only you will get Brahma Jnana. However, you are so fond of it, you can not part with it. Unless you part with it, I can not". (excerpt from Shri Sai Master's Shri Sai Leelamrutam)
