Thank you for your question!
There is symbolism in that explanation which will be fully understood by those who have experienced that.
The second Chakra symbolizes sensuality, reproduction, emotions. The first Chakra is survival. The third Chakra, is will power; the “black or white” sense of knowing what is right and what is wrong.
Most people in the world live and express their energies in the first and second Chakra. At that level, to practice celibacy is just a “bad idea,” something that will not be pursued at all. Sexual energy flows and it needs to be released. There is no inner knowledge of transforming sexual energy. At the second Chakra our emotions will run our life: “I feel like this, therefore; I act like this.”
This is what is called to act without restrictions, or as “you feel like.” It is a reaction based on stimulus.
Once the third Chakra comes as a way of expression, the energy is usually felt at the “mouth” of the stomach. It is the Chakra where we rely on will power, determination and a clear cut “law,” to act. To follow scriptures, to avoid temptations, to fight against “evil” etc. is part of that necessary expression to ascend. Usually Sakar Murlis are expressions of this Chakra. This is the Chakra to “reform” the self. Thought is important. To think things over before action is important, to review what the “holy book” or the “holy person” thinks is important in our decisions. We live in the world of “decisions.”
If you feel those characteristics as yours, you are perhaps there. Most BKs as well as spiritual minded individuals are there.
The 4th Chakra (Heart) is the origin of feeling love. Things are no longer thought out, but the “feeling” is important (not an emotion.) Expression of love becomes important. The “law” without “love” is perceived as foreigner. Sakar Murlis also have this ingredient (love) in them. It is the devotional love to God and the perception of something which is unusually beautiful, that is spiritual beauty. From that point is the expression of love through words (5th Chakra) and other means.
In my experience, the heart Chakra could be opened at the spiritual level by intense emotional suffering to the point of surrendering our thoughts or by an intense experience of love/bliss through the experience of God in meditation. There may be other ways, I don’t know.
It is good to understand that feeling love is not the same as knowing how to express it. There is a learning there, an art.
At this level of awareness you can do things out of love, when before; you could do things out of fulfilling a personal need as the main “reason.” This is why, someone who does not have a previous work on the self, cannot know “true love” for in the second Chakra, it is about emotions, sensuality and what it feels in the moment. That is what is known as “love” by the world in general.
In the 4th Chakra and above, you can experience the other things as well but the driving force is beauty, harmonizing beauty of inner expression beyond neediness, transactions, expectations and such things which “normal” individuals are used to.
Also, it is good to understand that “arriving” at one level does not mean that we can stay there. It is an “up and down” for most. That is why BapDada always talks about being stable, “constantly..”
