Matra sparshas tu kaunteya
O Arjuna, contact with the senses produces cold, heat, pleasure and pain. These are temporary; endure them patiently.
Modern Application: Emotions are temporary — stability comes from endurance.
Deep Wisdom: Krishna teaches emotional resilience. External experiences are temporary, so they should not disturb inner balance.
