What is Meditation

Meditation is YogYog is Union. You may ask- union of what? 

In response to this question, there are many traditional replies; some being- 

  • Union of the soul with God 
  • Union of Yin with Yang 
  • Union of Guru with Shishya 
  • Union of the Spirit-Body-Mind 

Are all of these answers right? And if so, then how do I, as an ordinary individual, know that I have attained that state? How would my life change if I were able to attain and experience it? 

Before seeking a reply to these questions, would you not like to ask what is it that separates us, in the first place; that we need to meditate to attain union?
