Stop this practice right away.

When do we practice something? There can be two answers relevant to this question.

• When you do not know and find it important/ or are forced to learn the subject
• When you deal with people, you find it important to suppress your feelings, perhaps they were inappropriate!

The first reason is when you are undergoing tutoring. But, today's world we aren't taught to develop qualities through practices.

We aren't expected to really feel what we say. So developing qualities, to such an extent that it transforms your character is not promoted in this material world. You are most likely expected to bear a temporary mask.
The second standard of practice is highly crucial for social engagement. This quote, elaborates more on this point: "We do not feel, but we do and say, just because it seems appropriate."

This is the mentality of people in the social world. This is the world of duplicity where all intentions are hidden.

Naturally, if the good ones are shown, the undercurrent driving people to engage one another is BAD.

In this case, you practice compassion. When you try to act compassionate to the other, in the social world, it simply means that you don't feel it.

So, when you don't feel anything and just exhibit it as an act, it remains significantly an act and not compassion!
