From the 1982 address on the occasion of the 9 Nights, Shri Mataji gave a new definition to original sin, which in it's generally known understanding, tends to infuse us with unnecessary guilt. However, the sin, if any, is only to believe we are powerless, individuals disconnected from the great unity. Some notable quotes from this address to Sahaja Yogis:
'That was the avidya, the artificial knowledge, the knowledge that “I am something,” that “I am the doer” - the ego. Till the animal stage there was no ego, and then the ego started growing. We can say that’s the beginning of the original sin: that “I am something.; I’m doing something; it’s I who can do it.'
