A little food for thought:

Vrttis refers to the different tendencies, which give rise to the mind expressing a variety of feelings & emotions. In order to achieve a serene consciousness, we have to be willing to change our behavior & approach toward the external world. Certain practices cultivate the mind & smooth the yogic path:

1. Maitri  —  Cultivation of friendliness toward those who are happy.

2. Karuna  —  Cultivation of compassion toward those who are in sorrow.

3. Mudita  —  Cultivation of joy toward those who are virtuous.

4. Upeksa  —  Cultivation of indifference or neutrality toward those who are full of vices.
