Om Swami
Why is a friend who only flatters me a bad friend?
Flattering friendship is dangerous
A friendship that only says pleasant things is very harmful, because it puts a veil over your faults, and the very thing you must work on becomes hidden. Stay in good company, so that good talk happens and good thoughts arise on their own.
A friendship where I keep telling you only good things is very dangerous, because the faults a person should work on get covered by a veil.
