What is the meaning of this Mañjuśrī teaching?

I read the following in the internet: > Sheng-yen renders the following teaching of Mañjuśrī, for entering > samādhi naturally through transcendent wisdom: > > > Contemplate the five skandhas as originally empty and quiescent, > non-arising, non-perishing, equal, without differentiation. Constantly > thus practicing, day or night, whether sitting, walking, standing or > lying down, finally one reaches an inconceivable state without any > obstruction or form. This is the Samadhi of One Act. > >[Wikipedia](https://en.wikipedia.org/wiki/Manjushri) What is meant, here, by the five skandhas (five components of life) as: 1. empty? 2. non-arising? 3. non-perishing? 4. equal, without differentiation?
