By focusing on the Shabad the limit is created. The Shabad can create a limit by creating inner experiences. Inner experiences create a thirst for more. The stronger the thirst, the more relentless we become. When this thirst is pursued passionately it becomes a vision which we personalise.
The Shabad generates its own emotional attachments creating inner experiences. Such inner experiences created by the Shabad excite the mann (mind).
As a human being, we are an accumulation of experiences. The more we experience the more we expand. The Shabad creates expansion, then the expansion becomes the Shabad.
The Shabad creates a model in the mann. The repetition of the model creates an experience. That experience becomes the expansion. We can only go as far as our personal experiences. Learning to apply the Shabad is key.
