Cause has to be real.
Imaginary causes of human suffering like fate, supreme creator and controller, planets in heaven, previous birth, karma etc.… are not real.
Ignorance, desires, attachments and aversions as the causes of suffering, are real and within the reach of individual to address. Every individual has ability to become free from ignorance, desires, attachments and aversions in order to mitigate suffering. Ignorance can be in various forms like self-ignorance, ignorance about nature of experiences, ignorance about the world etc.
Self-ignorance can be due to self based on self-conception, self-ideation, inner-self, self-image etc. and unrealistic ideas about self, for example, idea of being eternal immortal inner self independent of cause and conditions.
Ignorance about experiences can be in form of hypnosis and illusions due to which you may get drawn and lost into experiences without knowing correctly in the right context.
Due to ignorance about the impermanent and changing nature of life and the world, you may get attached and suffer due to desires and aversions. Due to ignorance, you may live and act against the supreme law of change and impermanence.
