Srimad Bhagavatam Canto 11, Chapter 23, Text 56

SB 11.23.56

na kenacit kvapi kathañcanasya
 dvandvoparagah paratah parasya
yathahamah samsrti-rupinah syad
 evam prabuddho na bibheti bhutaih
The false ego gives shape to illusory material existence and thus experiences material happiness and distress. The spirit soul, however, is transcendental to material nature; he can never actually be affected by material happiness and distress in any place, under any circumstance or by the agency of any person. A person who understands this has nothing whatsoever to fear from the material creation.
The brahmana has refuted six specific explanations of the happiness and distress of the living entity, and now he refutes any other explanation that might be given. On the basis of false ego, the bodily covering factually overwhelms the spirit soul, and thus one falsely enjoys and suffers that which has no real relationship with oneself. One who can understand this sublime teaching of the brahmana, spoken by the Lord to Uddhava, will never again suffer the terrible anxiety of fear within the material world.
