Think of the world as a sophisticated system designed by the Creator. The Gita explains the system, and the Ten Rules & 1 truth provide the operating principles for success, resilience, and fulfillment.

ममैवांशो जीवलोके जीवभूत: सनातन: | मन:षष्ठानीन्द्रियाणि प्रकृतिस्थानि कर्षति || 15.7|| 

The embodied souls in this material world are My eternal fragmental parts. But bound by material nature, they are struggling with the six senses including the mind. 

मामुपेत्य पुनर्जन्म दु:खालयमशाश्वतम् ।नाप्नुवन्ति महात्मान: संसिद्धिं परमां गता: ॥ 8.15॥ 

Having attained Me, the great souls are no more subject to rebirth in this world, which is transient and full of misery, because they have attained the highest perfection. 

एतैर्विमुक्त: कौन्तेय तमोद्वारैस्त्रिभिर्नर: | आचरत्यात्मन: श्रेयस्ततो याति परां गतिम् || 16.22|| 

Those who are free from the three gates to darkness endeavor for the welfare of their soul, and thereby attain the supreme goal.
