The esoterics of Taosim can be ignored.
I am sorry to disagree on this one,but to ignore the teachings , or works of Lao Tzu, is to lose a fundamental part of the I Ching.
Lau Tzu wrote two works , the Tao Teh Ching , and the Hua Hu Ching, they both go hand in glove with the I Ching.
To understand either you have to understand both, for to understand the way, is to understand there is no way.
The I Ching shows us that change is constant, it explains the interaction of Yin and Yang, the theoretical science of change, Lao Tzu's works show us how to apply the ideas and concepts of those theories, so as to return to "Wu Chi", which gives birth to Yin and Yang, in other words to return to a point of absolute balance and harmony, no ego, no emotional states, no imbalance, centered, calm and and free of thought , internal silence amidst the noise of the world around us.
