These days there is a huge emphasis on improving listening skills. It a common practice that when you are in conversation with somebody, it is essential that you listen that person very carefully. Otherwise the message is lost and the end result may not be what was intended during the conversation.
Same is the case with the inner voice. When you attend the conversation with the inner voice, the most important thing is that there should be a strong connect with it. This is impossible if there is not careful listening from your end. Since the careful listening is the solution, the listening atmosphere should be clear.
It is important that the place where you halt, sit for making a connection with the inner voice, should be clear of disturbances such as noise, people and objects. Although when you have practiced a lot and become a sort of expert in this task, all these factors will not matter at all. But to start with, it is important to establish physical clarity to establish a strong connection with the inner voice.
Another important factor is the establishment of mental clarity. It means that there should be no thought of sadness or excitement in your mind when you concentrate your mind on establishing a link with the inner voice. It should be bereft of any wavering. A calm mind will guarantee a speedy and strong connection. Although, just like in the case of physical clarity, the chaos at mental level will not bother you when you have practiced enough and have achieved expertise on the process.
Thus, for the beginners just like me, physical and mental clarity is an important for listening the inner voice.
