Development of Wisdom and inner Inquiry

But, there is a practice even superior to meditation.
The ultimate spiritual practice is the development of wisdom.
Wisdom emerges from inner inquiry. It is the spiritual practice of looking deep into the essential nature of everything. If you faithfully pursue this inquiry, you will gradually reach the supreme state of peace and bliss.
This is the unique goal of human life, a goal which all mankind will one day achieve.

Inner Inquiry - the Path of Wisdom
Sai Baba Gita pfd

I guess that is where this leads, I just don't understand what it has to do with a job, but maybe there is nothing to understand and it just has to do with feeling and worries in the mind we have to get aware of it and it is just part of that inner inquiry.

The Three Stages on the Wisdom Path

To reach the state of abiding inner peace, you begin by inquiring into the very heart of everything. This is the process of inner inquiry, the first stage on the wisdom path. Then you must make use of the deep insights you have gained by applying the spiritual teachings to every detail of your daily life. This is the second stage.  

If you continue with this practice unfailingly, then, in time, you will reach the goal of God-realization and enjoy unending bliss. This is the third and final stage on the wisdom path. (Baba Gita)

But it is both, in making use of the insights in the spiritual teaching and putting it in every detail of daily life and by doing it we get the deeper insight into the wisdom.
If we don't apply it that is just kind of not revealed to us and we have to follow the inner master and look at everything what comes up and that can be challenging, because we don't know the lesson ahead. 
The third state seems great, it is about bliss, if we continue with that practice unfailingly, in time we will reach the goal of bliss and the third stage of wisdom.
But it is not that easy, because it has on every stage obstacles...
It sounds that easy, that is kind of funny and in reality it is that different ... 

You can compare the first stage to the period of life when you are a student. As a student and spiritual seeker you are most active in acquiring knowledge. While you are in this stage you inquire into the principle which underlies everything in the universe.

You try to understand the deeper meaning of the great wisdom sayings, such as that thou art. Here, that ;refers to the eternal divine principle we call God, and thou refers to the immortal self, which is the one true reality of everyone. In this first stage you try to understand this saying, which states that the highest self and God are one and the same, and you look for this oneness in the core of everything. (Baba Gita)

 

That is nothing else but the inquiry into 'I am that' and 'that thou art'.

 

So, you start off by seeking the unity underlying everything in existence.

Then, having become aware of it, you live your life by applying this great truth to all your daily activities. This second stage can be compared to the period of life when you are employed and busy in your profession. If you have not pursued your education and earned good qualifications, you will not be able to find an appropriate position.

Therefore, in the first stage you acquire a good education and develop your knowledge so that in the next stage you can put that education into practice and use it to do your life's work. The third stage can be likened to the later period of life when you are retired and become a pensioner. (Baba Gita)

You see that is the profession he was must have been talking about. It is about putting that inner insight into practice and I am doing that mostly in writing about it and that is why he talked about getting retired and become a pensioner, it is not about age, but about wisdom. It is not so easy to understand that insight talk because we always see it first on the mind level that means the reality we live in our daily life only after long time inquiry we get aware of the fact that it has to do with wisdom... and not with age...

 

You receive a pension only after you have completed your working career. You start your career and gain employment, in the first place, only after you have successfully completed your education and acquired qualifications.
These then are the three stages in your path through life; namely, first is the stage when you are a student, then there is the stage when you are a professional, and lastly, there is the stage when you are a pensioner. Similarly, on the path of wisdom, you start out as a seeker, then you become a practitioner, and finally, you become a wise illumined one. In this final stage you enjoy complete peace of mind and realize the unity of all of creation. (Baba Gita)

And it is not about job too, but about wisdom, do you agree?
