The main theme is (Shiki-Soku-Ze-Kuu, Kuu-Soku-Ze-Shiki).
Heart Sutra says:
"You don't have 'yourself'. Actual existences are composed of a series of perceptions for example body, sense, imagination, association and thinking. All factors aren't yours, and also doesn't belong to you. But 'yourself' does not exist without these factors. That's why you aren't here eventually. In addition, these factors are also an illusion, unsubstantial one. By this wisdom, we can get out all sufferings and misfortunes."
