To fill your self with a quality or power, which you feel you do not have or one, which is lacking inside you, try the following exercise. Suppose you feel that you lack contentment (satisfaction). To increase this quality inside you, sit comfortably in a pleasant room with your eyes open.
Withdraw (remove) energy mentally from everything around you – turn your attention inward. You might think of how a tortoise withdraws into its shell to detach itself from the outside world, but carrying the experience of the world with it inside its shelter.
Create a point of consciousness. Focus on the centre of your forehead. Think of this point as a bright star, a sparkling jewel, a flame or a being of light. This will radiate positive energy, making you feel good about yourself.
Affirm (strengthen) this positive energy through positive thoughts and images about yourself such as ”I am a contented soul, I shower everyone whom I meet with the quality of contentment”, “I am a jewel of contentment”, or “I am the child of the Supreme Soul, the Ocean of Contentment”.
Focus your energy on contentment, and let this become the object of your meditation. As you focus, you will give contentment life, turning a thought into a feeling.
Experience this feeling by giving your conscious attention to it.
During the entire day, you could visualize yourself performing each action in the canopy (shelter) of the Ocean of Contentment.
Now perform this exercise for different virtues like cheerfulness, courage, humility (egolessness), tolerance, forgiveness, determination, etc. especially for the ones you think are lacking inside you. For the qualities already existing inside you, you could use this exercise to strengthen those features of your personality and bring them more into your actions and interactions.
