In plain words
Our food alone is the root of these evil feelings. There is taint in the food too. There is taint in the earning of the food too. There is taint in the cooking of this food too. There is taint in the one who cooks this food too. What we eat after offering it to God takes the form of prasāda. So, for every one of us, never mind what anyone thinks. We must pray in the right way and offer it.
That is why Mīrā offered the poisoned milk she was given to Kṛṣṇa. She saw nothing of whether it was poison or milk. Whatever she was given, she would say, “Kṛṣṇārpaṇam.” She would first set it before Kṛṣṇa and then eat it herself as prasāda. When she offered this prasāda to Kṛṣṇa, all the poison went to Kṛṣṇa and He turned blue. All the white milk went into Mīrā. At once she looked at the image in the shrine room. Kṛṣṇa had turned blue. She could not bear it. She had sent for white marble from Jaipur and had the image installed, poor soul. She wondered why such a pure marble Kṛṣṇa had turned blue. Grieving and grieving like this, she fell at Kṛṣṇa’s feet. The Mahārāṇā came. He came in a towering rage. He seized her by the hand and dragged her out. You cannot stay here. I am the Mahārāja. You are dragging all my honour and dignity in the dust. I had this temple built. You cannot stay in a temple I had built, he said. Mīrā was in anguish. She was grieving over why Kṛṣṇa had turned blue like this. Just then he had come in, saying, “My temple.” She felt a little hurt. Then she took courage. Mahārāṇā, you built this temple. You installed this image, it is true. But you did not build the temple of my heart. My Kṛṣṇa built it for Himself. He Himself is installed in my heart. No one has the right to tell me to leave it. O mind, why do you hold on to this sense of ‘mine’ here? Only through pride and the sense of ‘mine’ do all these troubles come to me: so she admonished her mind. ‘Chalo re man gaṅgā yamunā tīr’: O mind, go now. Go to that place of the Gaṅgā and the Yamunā, that is, to the place between the eyebrows. That is Prayāga. She did not try to buy a ticket to that Prayāga and go by train or bus. That whole triple confluence of the Gaṅgā and the Yamunā is within me alone. ‘Chalo re man gaṅgā yamunā tīr’: the Gaṅgā is iḍā, the Yamunā piṅgalā. The place of the brow between the two is the suṣumnā. That is Prayāga. Go to this place between the eyebrows called Prayāga.
