Sat Sri Akaal Pyareyo!
Pyaare Sevadaar Singh Ji,
Indeed, your experiences during Simran and listening to Keertan are a good sign that you are on the right path!! Actually, there is nothing wrong in sharing your experiences with the Satsangat and near-and-dear ones. There is a point in such experiences beyond which one cannot explain it to others or put it down in words! Since you are able to share your experiences with us by expressing it using language, there is nothing wrong in such a sharing. Once you reach the state of True Bliss, it goes beyond words, pictures and dimensions. For example, we all know about so many Saints and Bhagats who achieved enlightenment or union with God, but we don't really know what they went through. That cannot be known unless we reach that state of perfection. And it cannot be told to those who are not yet perfect because they won't understand. So, pyareyo, don't worry, just keep sharing till you can! Who knows when you'll fall into His loving embrace!!
But, sharing any spiritual experiences with common folk who are not really concerned about religion or spirituality or who are not yet ready, is mostly avoided. That's why Singhstah Ji warned you.
Gurbaani tells a seeker about the path to Waheguru, it informs one about the countless pitfalls. But it does not tell us about the unique spiritual experiences of our Satgurus. This is because such things are inexplicable!! And, even if our Satgurus could explain it to us, we would be daunted by the task of achieving those goals. Hence, in any religious belief system the actual state of True Bliss has never been defined. So, don't worry, if you can share something then it was meant to be shared!
By the way, we should actually share our methods of approach and how we tackle common pitfalls on this path, so that others can benefit from our experience. This is the need of the moment. Any experience, however mild or profound is worthy of being shared, if possible! So, please do share.
Bhull Chuk dee khima mangda haan.
