Brief explanation :

At the beginning of a class, the teacher and students generally recite this peace

invocation together. Both seek the Lord’s blessings for study that is free of obstacles,

such as poor memory, or the inability to concentrate or poor health. They also seek

blessings for a conducive relationship, without which communication of any subject

matter is difficult. Therefore, this prayer is important for both the teacher and the

student.

简析:
课前, 老师和学生一起吟唱这曲和平唱诵.共同祈祷神的祝福, 让他们远离求学路上的障碍, 诸如记忆力差, 专注力低, 健康问题等. 他们也在祈祷神的祝福, 让他们建立有益的关系, 没有这样的沟通, 任何事都会变得困难. 因此, 这首唱诵适合老师和学生共同吟诵.

Namaste Ji.

Manu
