Curb
Bhagavad-gita As It Is
BG Chapters 1 - 6
BG 2.8, Purport:
The Bhagavad-gītā confirms this: kṣīṇe puṇye martya-lokaṁ viśanti. "When the results of pious activities are finished, one falls down again from the peak of happiness to the lowest status of life." Many politicians of the world have fallen down in that way. Such downfalls only constitute more causes for lamentation.
Therefore, if we want to curb lamentation for good, then we have to take shelter of Kṛṣṇa, as Arjuna is seeking to do. So Arjuna asked Kṛṣṇa to solve his problem definitely, and that is the way of Kṛṣṇa consciousness.
