It's one thing to say that everything your soul needs for its process of awakening is right there in the practice of Stillness/meditation. It's quite another thing to put into coherent terms just what these packed away resources are. I can describe the impact that the unpacking has on a person's life: The deepening of sense of Self; the greater vitality and clarity of connection, but it is such a personal and intimate process that I hesitate to go beyond those generalities.
What I usually find is that those whose souls are already awakening immediately sense the validity of the claim and either begin practicing diligently or run the other way, depending on how they feel about the prospect of becoming more awake. It's the one's who are further from the goal who seem to have more difficulty in recognizing how something so simple and apparently inactive as meditation can have a significant impact on their lives.
One of the most difficult points to get across to some is that Stillness is not a struggle. The idea is not to repress our thoughts; to shove them down until they give up. Indeed, as soon as you start fighting, you've already lost. The trick is in letting them go. Just like a rock resting on the floor of a river lets the water go.
