It is not always the teacher who is important. It is the teaching. Lala babu, a rich Bengali Zamindar went to Vrindavan. While walking down the street, heard an old woman sitting on the roadside singing “bela je jai” meaning the day is gone! The words penetrated Lalababu’s heart. He felt deeply the impermanence of life, that his life was spent in indulgence and selfish greed. He went back home, gave away all his wealth and possessions and with only one blanket went back to Vrindavan and lived in deepest contemplation of the universal Lord. 

The beggar on the roadside  (teacher) remained a beggar, her words liberated a student!
