“The meditative mind is a pleasant mind, a stabilized mind. That state is called chitta-prasadana in Yoga-sutra 1.33. According to the sutra, such a state is obtained though the practice of

• Maîtri: Universal love towards those who are happy

• Karuna: Compassion towards those who are in suffering

• Mudita: Joyfulness at seeing others virtuous

• Upeksha: Indifference towards the evil in others

Without these practices the mind will never stabilize in meditation. The karmic debts we have not yet paid off will continue to disturb the meditation. While one is sitting with eyes closed, the mind will keep racing in all different directions.”
