Following are couple of shLOka from the mahAbhArathA, taken from Chathurvedi Badrinath’s “The Mahabharata – An inquiry in the human context”

अद्रोहः सर्वभूतेषु कर्मणा मनसा गिरा।
अनुगृहश्र्च दानं च शीलमेतत् प्रशस्यते।। शान्ति पर्व 124.66
(Freedom from malice towards any being, in act, thought, and speech; benevolence towards all; be sharing – this is sILa.)

धर्मः सत्यं तथा वृत्तं बलं चैव तथाप्यहम्।
शीलमूला महाप्राज्ञ सदा नास्त्यत्र संशयः।। शान्ति पर्व 124.62

dharma, truth, good conduct, strength and I (srI – all that which is desirable in human life) – all of us are rooted in shILa. Of that, there is no doubt.
{this slokA is through the voice of srI, and thus is the use of ‘I’ and ‘us’}

The first slokA defines shILa, which is said as foundational even to dharma (धर्म), which I am able to relate to quite much.

शीलं प्रदानं पुरुष तद् यस्येह प्रणश्यति।
न तस्य जीवितेनार्थो न धनेन न बन्धुभिः।। उध्योग पर्व 35.58
In human beings, it is sILa that has the chief place. If that is lost, a person’s life, wealth, and friends, all are meaningless.
