If we want to be free from physical, emotional and psychological problems then read the Bhagavad Gita. Today, we go to psychologists and therapists for solving emotional and psychological problems. The greatest psychologist and therapist is Bhagavan Sri Krishna.
An Example from Gita–
When a man thinks of objects, "attachment" for them arises; from attachment "desire" is born; from desire arises "anger" . . . From anger comes "delusion" ; from delusion "loss of memory" ; from loss of memory the "destruction of discrimination" ; from destruction of discrimination, he "perishes. " (Bhagavad Gita Chapter 2 Verse 62 and 63)
Bhagavad Gita is a text that understands the core issue. It does not provide illogical solutions through magic or prayers. Instead, it makes us understand what the real issue and tries to solve it.
Sri Krishna did not solve the problems faced by Arjuna through magic or by just lifting his hands. Instead, he made Arjuna realize what is wrong in his thinking. He made Arjuna realize the truth path. He made Arjuna realize his potential.
Kurukshetra is this world and we all are Arjunas who are constantly bogged down by numerous problems including physical, emotional and psychological. And Gita provides the solution to overcome these problems.
