Following are the simple techniques to manifest what you want in your life 

1.To manifest an object for example a car, close your eyes and hold the image of the object(car) in your third eye - agna chakara (the point in between the two eyebrows). Try to visualize it as clearly as possible for example, the model of the car, the colour of the car etc, feel the new brand car., feel the smell of the new leather seat . Be in this state for sometime and let it go to the universe. It is now the universe job to bring it to you. 

You now start doing your routine work.The Universe knows infinite ways to bring this object into your physical reality.So, don't bother too much about how it would manifest for you,because human brain has limitations.Just note the time taken for you to manifest this into your physical reality.Keep practising this technique regularly as consistency would teach you more than the written words. 

This technique will be even more powerful when done after a small meditation. Medidate for few minutes and do the manifestation technique.This will leave your mind in a receptive state,meaning, the mind becomes very pure.And manifestation becomes almost instantaneous in this state of mind. 

2.Similarly, there is another easy but powerful technique for manifesting your goals and desires. It is called the "Synchronicities method of manifestation" 

Now, take a pen and paper and write down all those moments in your past life where you have been absolutely happy like, getting a car, falling in love,someone or a group of people appreciating your effort,your achievements or anything that has made you feel absolutely happy at the bottom of your heart. 

The second step is to write these synchronicities in a book or journal or a diary.Now, take the paper and read out loudly to the universe by saying the following word "Dear universe, please begin bringing synchronicites to me involving"(say out loudly all the synchronicities that you have written in the paper) 

Thirdly keep this paper inside the book/journal/diary in such a way that a portion of the paper is projecting outside the journal and some contents are visible to you. 

Keep the book (with this paper inside) in a shelf or your study table or any other place where you can see it often. 

Before you could realize,in ways that you would have never imagined, the Universe will bring these synchronicities to you in your physical reality.....Happy Manifesting!
