Refer to Imam Khomeini's advice and writings
When we say that preserving and guarding the Revolution was entrusted to youth by Imam (r.a.), this does not mean that those who are not young do not have any mission. They do have a mission. This is everyone’s mission. All people - including eighty-year-old individuals, those even older than that, teenagers, men, women, outstanding personalities, ordinary individuals and all the people in the country – have the mission of preserving their Revolution. This is the responsibility of all of us.
However, youth are the leaders. They are the engine of the movement. If the young generation did not exist, and if they did not want to take action, the movement would have stopped. The wisdom, ideas and experience of the elderly proves useful only when the youthful movement of youth exists. The leaders of this movement are youth. Therefore, you youth who have not seen Imam (r.a.) are addressed by him. Imam (r.a.) has spoken to you. He has spoken to you. You should refer to his statements.
