COMMON MEDITATIONAL STATES OF MIND
Vibrations
There are two natural places in our body that vibrate or where there is activity. One is the heart and the other is the Sikhar (where the vibrations are more clearly felt at birth). The vibration in the sikhar is natural to those who progress in the path because with the steadiness of meditation in the heart, the other one also vibrates.
The experience of vibrations during meditation is indicative of the Pranahuti at work.
Jerks and similar feelings are common in the path and they are indicative of the cleaning of the Nadis spoken of much in traditional literature. It gets done naturally (Nadi Shuddhi) in our system without much effort from our side. The feeling of purity gained is an indication of the starting of the Yatra though we find other centres are also activated. Jerks are due to blemishes in us which obstruct the flow of Pranahuti.
Ajapa and Anahad conditions do not last long in our system.
