Stopping Four Things

“In Bhagavad-gita the Lord points out that a person who is serious about advancement in spiritual consciousness should always consider the four pangs of birth, death, disease and old age. The materialist advances in many ways, but he is unable to stop these four principles of suffering inherent in material existence.” (Shrila Prabhupada, Shrimad Bhagavatam, 3.31.23 Purport)
