Virtuous meditation can be practiced by a person with a physical constitution who can keep his thought-activity from drifting and concentrate solely on the nature of self. When the soul gets rid of all auspicious and inauspicious intentions and dilemmas, and attains a state of unbiased absorption in all bonds of karma break down. In fact, meditation entails forgetting all worries, intentions and dilemmas, and stabilizing the mind. It involves contemplating about the nature of soul, thinking of the difference between soul and matter, and concentrating on the true self.
Meditation purifies the mind, speech and body.

Meditation is the only means to stabilize the mind. The last two are auspicious because they help destroy karma. The Sanskrit word aarta means sorrow.
