If all the available wisdom which philosophy holds were to be likened to a large jig-saw puzzle, then Vedanta philosophy has all the pieces for the picture, which we are likely to need in our lives.  It deals with the following matters in detail:-

1. Knowledge about the soul’s journey in this world, which may require many human embodiments.

2. The accumulated effect of our past actions, in all embodiments, and how to deal with them.

3. The nature of the human being - body, senses, mind, intellect and soul - and how they work together.

4. Devotion and the nature of it.  5. The way to understand renunciation.  6. The nature of illusion.

7. The nature of the three forces which govern both the universe and human psychology.

8. The value of meditation or control of the mind.  9. The nature of the true Self.

10. How knowledge and action need to be understood and the way they can lead us towards perfection.

11. Ignorance and its effect on the human race.  12. The value, nature and types of true worship.

13. How many ways the Divine manifests in the world.  14. How to become free while living in the body.

15. The relationship between the Universal Self and the individual Self.

16. A comparison between those traits which help our progress and those which retard our progress.

17. Types of discipline and how to lead a disciplined life in all aspects of it.

18. How to take advantage of all situations in life to benefit the progress of the soul.

Above are the main topics which are dealt with.  There are many other issues which will make sense to those who have attempted, for many years, to understand and practice the above list.

Most belief systems which have arisen in the Middle East and Europe in the last 4,000 years or so, have the basic approach of taking control of the choices which individuals and society make.  Vedanta, on the other hand, does not take this approach.  Therefore we find that there is no attempt at proselytising or to decide for the society or individual what choices they should make.  This has avoided such things as conflict and persecution of both individuals and whole countries, where Vedanta has been the influencing factor.  Those who live within the confines of the control system approach cannot easily realise this fact.
