Ayurveda can show us how to replace unhealthy habits with better ones by using self-acceptance, awareness and tenderness rather than forcefulness and willpower. These energies create an inner environment within which positive change can spring naturally. There is no struggle about it and change comes about gradually and sustainably.
Ayurveda encourages us to ask basic questions about any habit that we have, such as what purpose it serves and whether there are there better ways to serve it. Could it be that sweetness can come from more nurturing companions, for example, rather than from another cookie? By putting our habits into a larger context like this, we can understand them better and respond more creatively to whatever triggers them.
