“When disturbed by negative thoughts, opposite [positive] ones should be thought of. This is pratipaksha bhavana.” (Swami Satchidananda translation)
“When doubt or wayward thoughts disturb the cultivation of a calm mind, generate the opposite: a counterforce of thoughts, images, or feelings that have the power to uplift, invigorate, inspire, and steady the mind. This is pratipaksha bhavana.” (Rev. Jaganath translation)
pratipakṣa = the opposite
bhāvanam = cultivation
In this practice, we consciously choose to replace a negative, unhelpful thought with a positive one. For example, instead of focusing on a thought such as “This world is a mess,” we choose something like “This world has so much beauty in it.” We might go on to think of all the beautiful places or situations we know. Instead of a thought such as “My son is ruining his life,” we choose something like “I love my son no matter what.”
This practice can also be used with thoughts about ourselves. A thought like “I’m so weak” can become “I’m getting stronger each day.” The positive thought generates a positive energy within us to take whatever actions we’re able to take while letting go of whatever is beyond our control.
Repetitive thoughts form what Yoga calls samskaras. These samskaras are like ruts in the mind: We have a tendency to fall into them over and over because that is what we have done in the past. The negative ruts are well-worn. However, the good news is that, with regular practice, we can form new ruts that move in a healthy, positive, uplifting direction.
Try this: Write out two or three negative thoughts that plague you. Then, write the positive thought for each one you wish to use instead. Begin countering the negative thought with the positive one as you go about your days.
