This is very broad topic. We had a discussion on one day and one of my family friends helped me to understand the concept as shown below:
Knowing about atma and understanding the concept of staying in true happiness (bliss) in every moment of the life by playing/acting(performing actions of) the role at that time to a near perfection. The role can be son/daughter, husband/wife, father/mother, and friend/a fellow human being. Every human being can only learn atma gnana (knowledge of soul) after meeting a real spiritual guru and receiving knowledge. In order to get to real spiritual guru one has to earn the qualification. The qualification can only be attained by having discipline in life, implementing rules/knowledge of right action (dharma gnana) and doing sadhana with the body, mind and intellect (BMI). Three different ways of doing sadhana are pooja(praying god), Japam( chanting god's name), and chintana( meditation). The sadhana helps in purifying thoughts and deeds of human being. There is a lot of literature on knowledge of right action (dharma gnana). Almost all the religion’s teachings and books has knowledge of right action.
The article Heart and Soul (n.d) describes that the light and consciousness of the soul pass through every part of the whole body but most of the time soul resides in the heart. The article also mentions that every human being deep within themselves has infinite peace, light and bliss. In order to get infinitely more peace, light and bliss one has to meditate in the heart. The meditation in the mind gives limited peace, light and bliss.
Now the question is how to meditate in the heart and in the mind? I will try to find out and post in the new thread.
