What was Frankl's advice to his fellow prisoners when their morale was low in Man's Search for Meaning?

Frankl's advice was that prisoners should embrace what freedoms they had, even within the limitations of the degraded conditions of a concentration camp. While many people descended into apathy and even cruelty, Frankl says there were people who chose to reach out to others and be compassionate to prisoners even worse off than themselves despite their circumstances.
To give up on life entirely is to be robbed of one's most precious possession—one's inner freedom. Frankl believes that this is one thing no one else can take from an individual without that individual's consent. Even when imminent death is inevitable, a person can still choose to face death with courage and dignity. In essence, his advice is that people always have a choice and to exercise the power to decide how one will face life is important if one wishes to live a meaningful life, even in the face of suffering and evil.
