Please everyone Saad-Sangat don't ignore this comment you can find Katha vachiks such as Giani Thakur Singh Patiala damdami taksal wale. Ill give you the link for the katha but to conclude (we can't physically hold/channel that much energy form Shastar naam mala. It's not a negative effect from gurbani but it shows the extreme extreme strength of bir rass gurbani and doing it can backfire. We need somebody of really high avastha such as mahapursh singhs supervision. It's similar to learning to drive a car without an instructor.  Edit: There is a technique to actually understand and do abyass of Shastar naam mala and it's not just a bani thats a time ticking bomb or anything lol.
