Just thinking 'I am not this body' is not going to serve the purpose. We simply have to be engaged in the service of Krishna that automatically will transcend the bodily platform and situate us in spiritual identity.
Always live in ISKCON and never leave ISKCON because ISKCON is the lotus feet of Srila Prabhupada. Serve Srila Prabhupada in your whole life.
Determination should move mountains to make way for devotees to progress towards the lotus feet of Krishna.
When all material advancements utilized in spiritual need that is the real advancement of human civilization.
