Kabbalah is a wisdom that reveals the comprehensive reality that is normally hidden from our senses.
The reality that exists within our ego is changing day by day and every moment. If we rise above our egoistic feelings, we attain an external reality, the true reality. This reality does not change and is indeed eternal. The method of achieving this attainment is called the wisdom of Kabbalah. Therefore, it is considered a hidden wisdom that uncovers the hidden reality for us.
