The interest of the disciple is always to accumulate an increase his force (as compared to others), a flawless sexuality, perfect health, long life and mental ability in order to paralyze his opponents.

Does Taoism, Tao-te ching, offers such advantages? Will we be more efficient in our relations with others, more competent, stronger?

Once Master Lu said: "The advantage of following Tao is purely individual. You become more astute according to your ideals and wishes, and perhaps more efficient when it comes to attain your goal that makes you happy".

Here "individual" means a feature related to one's inner self. In other words, you gain something but only on a subjective level. The relation with others may be transformed too, but not necessarily giving  you a privileged position as opposed to them.

In short, you won't get stronger, tougher, by all means; you won't be able to dominate the others. Perhaps, quite the opposite, you will be "softer", as the momentary tendency dictates.

But you start to make peace with yourself, with your inner self!
