The twenty-eighth yoga sutra explains about the adept way in which a yogi must handle the latent impressions and cautiously eradicate them. The gap or fissure between the seer and consciousness increases by the breeding of agitations and disharmonies. A yogi needs carefully to extinguish these latent impressions in order to establish peace and serenity within the soul and seer. By essential vigour and life-force in yogic practice, the punctures of consciousness can be closed.

In the same way as the sadhaka strives to be free from afflictions, the yogi must handle these latent impressions judiciously to extinguish them.

The gap between consciousness and the seer can rear disharmony and disturbance in one`s self. As fire is deprived of fuel, likewise, the yogi has to remove the latent impressions from the consciousness and extinguish them, for it to be in harmony with the seer.

Patanjali advises the yogi to eliminate disturbances by reintroducing yogic disciplines with faith, vigour and vitality. As the sadhaka earlier strove to rid himself of the sufferings of avidya, asmita, raga, dvesa and abhinivesa, the exalted yogi must, through practice, press, dry out and close the perforations in the consciousness.

iv. 27 stated that subconscious impressions surface in the form of intellectual pride, which hinders progress towards the goal of union with the divine seer. As roasted seeds do not germinate, so the fire of wisdom must burn out impressions and ambitions, ending their power to generate disturbing thoughts, so that the consciousness maintains its union with the seer forever.
