The Psychology of Jealousy and Envy

These tragic stories reveal a chilling truth: jealousy and envy, when left unchecked, can lead to devastating consequences. These complex emotions are rooted in human psychology.

However, while they are often used interchangeably, they have distinct psychological foundations.

  • Jealousy arises from fear of losing something valuable, often due to insecurity or past betrayal, triggering stress hormones and emotional distress.
  • Envy stems from desiring what others have, either driving self-improvement or fostering resentment. Studies link envy to social comparison and emotional pain, highlighting its psychological impact.

Both emotions can be destructive if left unchecked, leading to obsession, depression, or even violent behavior. From a spiritual perspective, jealousy is a low-vibrational energy that can open the door to negative influences.

Many religious traditions warn that unchecked jealousy can lead to darkness, not necessarily in the form of literal demons, but as an internal corruption of the soul.

In Christianity, envy is considered one of the seven deadly sins, believed to distance a person from God’s light. Some even view extreme jealousy as a foothold for demonic influence, as it fosters resentment, manipulation, and destructive behavior.

“Envy is the art of counting the other fellow’s blessings instead of your own.” ~ Harold Coffin

In other spiritual traditions, such as Hinduism and Buddhism, jealousy is linked to ego and attachment. It is seen as a sign that a person is out of balance, too focused on material desires or external validation rather than inner peace.

Some teachings suggest that harboring jealousy can attract negative karma or low-energy entities that feed on emotional turmoil. Even in folk traditions and indigenous beliefs, jealousy is sometimes associated with the “evil eye,” the idea that envy can carry an energetic force capable of bringing harm.

Ultimately, whether one believes in literal possession or not, jealousy and envy have a powerful spiritual impact. Jealousy kills peace and relationships, clouds judgment, and blocks personal growth.

Gratitude, self-awareness, and cultivating an abundant mindset rather than a scarcity mindset are some of the best ways to counteract jealousy. Many cultures also recommend using spiritual cleansing rituals, prayers, or protective talismans to ward off the effects of jealousy (evil eye).

Be mindful of how much you share about your achievements, especially in environments where competition is high, like the workplace.

#5. Avoid engaging

Some people thrive on stirring drama. If you sense envy from someone, create healthy boundaries. Respond with kindness, but avoid giving them emotional power over you.

How to Heal Jealousy and Envy

Understanding the psychology of jealousy and envy can help us manage these feelings constructively through self-awareness, emotional regulation, and healthy coping mechanisms.

“The jealous are troublesome to others, but a torment to themselves.” – William Penn

If you struggle with jealousy and envy, recognize it as an opportunity for growth. Instead of suppressing jealousy, ask: What is this feeling teaching me? Often, jealousy reveals unfulfilled desires.

Use it as motivation for self-improvement rather than resentment. Jealousy often stems from scarcity thinking — the belief that someone else’s success diminishes your own.

To counteract this:

  • Overcome Envy: Free yourself by appreciating what you have and finding joy in others’ success, not bitterness.
  • Overcome Your Inferiority Complex: If you constantly feel inferior, you’ll find reasons to feel inferior in everything. Recognize your strengths and weaknesses without shame.
  • Overcome Your Limiting Beliefs: Rewrite the negative messages holding you back, break free from self-limiting beliefs, and stop being your own worst enemy.
  • Stop Caring What Others Think: Trust yourself and start living authentically. Stop living a shadow life and make choices that reflect who you truly are.
  • Overcome Insecurity in Relationships: Rewire the patterns behind relationship insecurity, so you can trust, relax, and love without second-guessing every word, action, or moment apart.
  • Start a Daily Gratitude Practice: Intentionally acknowledging your blessings, big or small, can enrich your life each day.
  • Cultivate an Abundant Mindset: When you see someone succeed, send them a silent blessing instead of feeling envious.
  • Celebrate Your Achievements: Stop downplaying your successes and start giving yourself the credit you deserve — acknowledging your achievements builds the self-belief and confidence you’ve been missing.

Recognizing jealousy in yourself and others and learning to handle it gracefully can help you navigate relationships and workplace dynamics more effectively.
