No one knows the full capacity of the Shabad but the power of the soul means the possibilities are vast.
The Shabad can create opportunities which often lay in concerns, worries and expectations. By meeting the needs the Shabad reaches its full capacity. We need reasons to create expectations, then these reasons become a compelling force. The Shabad expands beyond expectations and removes barriers or limitations. The barriers become raised or extended and bring God to a human level.
The Shabad stabilises emotions but it doesn’t remove them. The Shabad doesn’t destroy anything, it only transforms but it requires emotional acceptance. The intensity and duration of the emotion bring the Shabad to its fruition.
