One of the teachings or practice of yoga is the observation of Saucha – Internal and external purity or cleanliness.
Internal purity or cleanliness is to maintain purity or cleanliness of the mind by eliminate impurities from the mind, to allow the mind to be able to see the truth of things as it is, without being influenced by any impurities.
External purity or cleanliness is doing our best within our capability to maintain cleanliness of the physical body, the living environment and the yoga and meditation practice space to allow ourselves to be able to perform physical form of yoga and meditation practice in a clean and conducive practice space, and be able to perform all our duties and responsibilities towards ourselves and others with a healthy physical body.
There’s no limitation for the internal mind purification or cleanliness, except lack of non-attachment, self-awareness, introspection, self-discipline, self-control, determination and perseverance in oneself. Meanwhile there’s some limitation for external purification or cleanliness as there are external elements or factors that are beyond the control within our capability. Although most untrained minds will be affected and influenced more or less by external conditions, that’s why external cleanliness is an important factor in yoga and meditation practice, but, all kinds of external limitations couldn’t and wouldn’t stop one from achieving internal purification or cleanliness, if one knows what is non-attachment.
I’ll do my best to have a clean living and practice space for my personal physical yoga practice at home and while travelling. But, if a clean living and practice space or environment is not available for me to be performing physical form of yoga and meditation practice, it’s okay. It won’t stop me from performing internal yoga and meditation practice continuously.
For running the yoga retreats, I’ll do my best to provide and maintain a clean living and practice space for the retreat guests. But, what is beyond the control within my capability, I’ll let it be and allow the guests to practice non-attachment and learn to accept the reality that is not necessarily the way that how we would like it to be.
By having a clean living space to live in, or having a clean body for achieving physical good health and high fitness level, or having a clean practice space to perform physical form of yoga and meditation practice doesn’t guarantee that one will be free from ignorance and suffering. It is the internal practice of non-attachment, non-craving and non-aversion that allows the mind to be free from ignorance and suffering, under any conditions and situations, whether a clean living and practice space is available to us, or not.
