Idaṃ pure cittamacāri cārikaṃ,
yenicchakaṃ yatthakāmaṃ yathāsukhaṃ.
Tadajjahaṃ niggahessāmi yoniso,
hatthippabhinnaṃ viya aṃkusaggaho.
This mind that wanders wherever it wishes, desires, wherever it sees pleasure, I will first make it steadfast. I will train it thoroughly like a mahout with a goad trains a wild elephant.
Strong determined efforts are needed to change this habit pattern of the mind. Stop the mind constantly wandering into the past or future. You train your own mind to remain in reality of the present.
Be master of this present moment, and be master of your future.
By experiencing this inner reality of sensations arising, passing away, Vipassana trains us to be aware – with equanimity - of the true, impermanent nature of things, every moment. This is experiencing impermanence or anicca (*), the practice of Vipassana.
A moment of purity from Vipassana practice has a strong impact on old impurities accumulated in deeper levels of the mind. Accumulated impurities and this moment of purity come in explosive contact as negative and positive forces - like eruption of a volcano within. As a result, some deep-rooted impurities may surface as various physical or mental discomforts - such as pain in the legs or in the head, or fear or agitation. What seems a problem is actually signs of progress in meditation. When cutting open an abscess, pus is bound to surface. Similarly, during this Vipassana surgery of the mind, some underlying pus is coming out of the wound. Although unpleasant, this is the only way to get rid of the pus, to remove impurities that for long are cause of one's misery.
The mind has to be fully attentive to subtler sensations continuously, their arising and passing away, without interruption of thoughts, for longer periods. This is Vipassana.
