You have to know that the mind is almost always impure, bringing in dark and bad thoughts. Even when it is not doing this, it is still a victim to doubt, jealousy, hypocrisy, fear and all that. All negative things first attack the mind. You may reject them for a minute, but the next minute they knock at your mind's door again. This is the nature of the mind.
But the heart is much, much purer, because affection, love, devotion, surrender and other divine qualities are already in the heart. Even if you have fear or jealousy in the heart, the good qualities of the heart will still come forward. But again, the heart is not totally pure because the vital being is around the heart. The lower vital, situated near the navel, tends to come up and touch the heart centre. It tries to make the heart impure by its influence and proximity. But at least the heart is not like the mind, which is always opening its door to impure ideas.
Even better than the heart is the soul. Here there is no impurity. The soul is all Purity, Light, Bliss and Divinity. When you say, "I have no mind," this does not mean that you are becoming an animal again. Far from it! You are only saying, "I don't care for this mind, which is bringing me so much impurity and torturing me so much." When you say, "I have the heart," you feel that the heart has some purity. But when you say, "I have the soul," you are flooded with purity. Then, after some time, you have to go deeper and farther and not only say, "I have the soul," but "I am the soul." The moment you say, "I am the soul," and you meditate on this truth, your soul's infinite purity will enter into your heart. Then from the heart, the infinite purity of your soul will enter into the mind. In this way you will purify your mind and your heart and you will be able to have a wonderful meditation every day.From:Sri Chinmoy,Promised Light from the Beyond, AUM Publications, New York, 1973
