Whenever something (thoughts, emotions etc.,) bubbles up in the mind, at this time we need to firmly think that all this is not our real form and try to be separate from it. As we stop getting mixed up with thoughts, emotions, imaginations, forces of Prana of the mind and intellect, it will still continue to bubble up. This will be of many kind. Sometimes it can become so strong that poor Sadhak can get lost and confused. Even then, these moments are truly and appropriately testing his strength and determination in life. Only such a Jiva who understands this in the heart, that the true life is to take such a step in the path of the development of life, will survive this test. Others will perish.
What we need to do is to develop the habit of the mind to think only of one subject and prevent it from thinking of variety of things. Try to keep the mind on one subject and if it moves away from it, bring it back to the same subject. If it is possible to keep the mind in the Chetna-Smaran or the holy Bhavna of Guru, just do that. It may become or happen easier. Here Sadhak needs to be more alert, careful, with the Bhava of knowledge.
Our only work is to see that our mind stays engaged continuously in Sadhana of life. Know that knowledge and awareness of this fact need to be remembered and put in practice of our work, relationship and behavior in the dealings of society.
Nature of the mind is to run aimlessly but if we can concentrate and focus on only one thing, mind may find it easier.
