The joy that we feel seeing the happiness of other beings is the pure joy unadulterated by self-interest. Feeling pleased at other's happiness is a great virtue!
On the other hand, the joy one feels while seeing others fail, suffer or get hurt; the sadistic pleasure one takes when something goes wrong for others, is all beastly happiness derived from the suffering and misfortune of others. Instead of feeling sympathy for others suffering, why does it evoke feeling of happiness and pleasure within us?

Come, let’s introspect that ‘are we finding happiness only at the suffering of others?’
Say, someone comes and says that so and so person made good money in his business, does it make you unhappy?

Generally,
1.For whatever reason, when we can’t digest other’s success, it leads to jealousy.
2.Due to jealousy, for no reason, the competition arises in our mind.
3.Due to feeling of competition within us, our intellect keeps showing negative about them.
4.Constantly harnessing negative feelings for others, we begin to hate them.
5.As the feeling of hatred for them grows in our heart, it leads to secret enmity with them.
6.Due to this feeling of enmity, we wish their downfall.
7.And when we see our wish seem to come true, we feel happy at the suffering of them.

Thus,
•Inspite of having all the money and being blessed with enormous worldly pleasures and comforts; if listening to anything good about someone else generates fear within us that ‘what if this person will become bigger than me?’, we must know that we are jealous. Our jealousy makes us find happiness at the suffering of others as it makes one feel victorious merely by seeing others saddened after defeat.

•It also happens that when one is suffering from embarrassment in life, he wants to see everyone suffer as him. He therefore finds happiness at the sufferings of others, as his awkwardness gets eased out a little during such time.

•In many cases, for no good reason, one naturally finds happiness only at the sufferings of others. Their intellect only is such! Good intellect is one that always looks for other’s happiness, finds happiness in everyone’s collective happiness. But if the intellect is not good, we look for negative happiness i.e. happiness derived from suffering of others.

Do we need to find such negative happiness at all? Let’s find out...
Certainly not! Negative happiness is very short-lived, but the suffering it brings, in the form of fruits of the demerit karmas that we bind on account of such negative happiness, is harsh and severe. Therefore, it is in our own interest to maintain humility and let others progress.

•Let’s allow others to succeed in a nice and happy way rather than beat people’s success and make them fall behind in their life. This will allow us to live peacefully and in ease. For the people whose success we are unable to digest, pray that, ‘May all of you prosper well.’ We may find it difficult initially, but continue to do so. Those who enter a ‘racecourse’ (competition) have to ultimately suffer lot of pain. It is just not worth it. Instead, simply watch the competition and ‘see’ which horse comes first in the racecourse. The one who simply ‘sees’ has no pain or suffering.

Would we like it if one is happy seeing us suffer? Then how can our heart permit us to be happy at others suffering? Religion teaches us to remain sincere to our self as well as to the entire world.

•If we are experiencing constant embarrassment in our life, it becomes all the more important that we minutely study in great detail that, ‘Any person that I am interacting with, are his feelings being hurt by me in any way?’, because from our experience, we now exactly know how it feels.

Morality means one’s mind is set on not causing a loss to anyone even to the slightest extent; to not take anyone’s happiness away. Finding happiness at the suffering of others is being immoral and it will only extend our current misery furthermore.

•There are two types of intellects: the misguiding one and one that does not misguide. The misguiding intellect is indeed selfish and it makes us do things of our self-interest all day long. As this intellect increases, internal burning increases all the more. Whereas if our intellect is one without misguidance, we experience positive happiness with such intellect. To have an intellect without misguidance, we ought to practice an obliging nature and honesty in life, and dress them with the clothes of sincerity and morality.

The practices we must resort to for our progress in life.

Maintain the awareness not to hurt any living being, even in the slightest degree, through your mind, speech and actions. We will make good progress when this principle remains firm in our conviction and awareness. Our personality begins to shine when we move away from practices that yield negative happiness derived from other’s suffering; and instead move towards adopting sincerity and morality in life, by sitting in the company of and in proximity of Gnani, the Enlightened One, in whom the attributes of morality and sincerity are apparent. Just keep observing Gnani; this will help us seek pure joy, unadulterated by any kind of self-interest, for:

•Gnani’s method is to win over the world by letting others win!
•Gnani’s intent is always, “May the world attain the happiness that I have attained.”
•Gnani has become free from all intellect. In them, all that flows is compassion, love and their unwavering awareness of how people in this world can achieve salvation!!!

Author's Bio: 

Ambalal M. Patel was a civil contractor by profession. In June 1958, spontaneous Self-Realization occurred within Ambalal M. Patel. From this point on, Ambalal became a Gnani Purush, and the Lord that manifest within him became known as Dada Bhagwan. A Gnani Purush is One who has realized the Self and is able help others do the same. Param Pujya Dada Bhagwan used to go from town to town and country-to-country to give satsang (spiritual discourse) and impart the knowledge of the Self, as well as knowledge of harmonious worldly interactions to everyone who came to meet him. This spiritual science, known as Akram Vignan, is the step-less path to Self-realization.
