It is the illusion that allures one to enjoy the mundane objects in a futile effort of satisfying the unceasing demands of his senses within the waking or dream. A person within the illusion becomes intoxicated of lust, greed, anger, attachment, false ego, enviousness, stubborn mindedness, and their numerous variations within the illusion.
Consequently, the individual self gets caught in the illusory cycle of birth, old age, disease, and death within the illusion. This is illusion, by which the consciousness is forgotten; emotional attachment and love of duality is born.
The ignorance of the true self is cause of duality. The duality is cause of illusion. The illusion is the cause of experiencing unreality as reality.
Because of this pluralistic phenomena of illusory -vision, the material happiness appears to be followed by sorrow. If there is laughter, there is a cry; if there is a birth, there is a death; if there is a rich, there is a poor; so on and so forth.
Everything in the waking or dream experience is in the state of constant flux; there can be found no everlasting happiness. The ego is in the control of evil passions, evil intent, and duality.
Everyone wishes for happiness, pleasures, joy, peace, etc. and none asks for suffering, misery, etc. But in the wake of pleasure, there comes suffering. The pleasure and pain co-exists within the illusion. People do not understand this. Therefore, there is necessary to realize the fact that mind, which appears as waking or dream is mere illusion.
There is a need to know fact that, the ‘I’ is not limited to the physical entity alone but ‘I’ is the mind, which appears and disappears as waking or dream. If there is no ‘I’ then there is neither waking nor dream. If there is ‘I’ then there is mind. If there is mind then only there is waking or dream. Therefore mind is not limited to the physical entity alone. Therefore, there is a need to analyze “What is ‘I?”, before indulging in pursuit of truth, in order overcome all the flaws in understanding and assimilating the non-dual truth. The ‘I’, which appears as mind is impermanent. The formless substance of the ‘I’/mind is real and eternal.
