Sensory Meditation

All consciousness is made up of external or internal sensations, which are put together in series as thoughts and in parallel as feelings. To focus on the whole of our consciousness, meditation should therefore focus on sensations, on how they feel imbalanced and how they would feel if balanced.
Most of the time, sight, sound and touch are the only we can focus on, and focusing on all three will make us most conscious (e.g. mantras+mudras+nimitta), which also increases lucidity in dreams.
Sight is the more cognitive of the senses, touch, the most physical, and hearing, the most emotional, and if we are imbalanced between cognition, physique and emotions, we should focus most on the sensation of whichever is most lacking, or, should that be too hard, with whichever is least lacking. If our imbalance lies in the lack of emotions, however, then this will almost always be because of a lack of either cognition or physique, as emotion lies in between. If the imbalance is towards the cognitive, focus firstly on touch and then on hearing. If the imbalance is towards the physical, firstly on sight and then on hearing. The senses should not be seen merely as different entities in themselves, however, but as different aspects of the sensorium.
