It is mind that holds on, it is mind that forms perception, it is mind that defines what is good and what is not, it is mind that creates feelings of happiness and grief, it is mind that desires and hates.
Mind always worked with such dualism, and it leads to subjective perception, leading further to bondage and pains. It is these desires of mind that are called ‘samsara’
Perceptions are formed by the mind, in the mind. Perceptions of happiness, grief etc formed in mind related to acquisitions and possessions of objects of desire, including knowledge, are truly transient. No objects, acts, or events external can have any significant influence on you unless you let it.
World of subjective perceptions formed by mind is the great illusion ‘Maya’, not the world, outside of you. What is outside of you does not truly affect you unless you let it.
True renunciation is renunciation of these desires and subjective perceptions. When you realize this, when your mind withdraws from these desires and subjective perceptions, you are beyond renunciation and you are liberated from the illusion.
After that, one can remain where one is, continue to do whatever one does, with no bindings of desire
People like us, who believe in physics, know that the distinction between past, present, and future is only a stubbornly persistent illusion – Albert Einstein
