Renunciation doesn't mean giving up things externally but rather it means diligently pulling out the weeds from the heart.

Out of all the opulences of a living entity its humility which pleases Krishna. Other opulences can also please Krishna if offered with humility.

Renunciation means death of false ego.

Service is life. No service means, spiritually no life.

What touches our hearts and impresses us deeper is sacrifice and humility, when we see someone accept the higher principle of cooperation, putting aside his/her own achievements.

All beautiful forms of this world are in the process of transformation. Nothing is stable. With every moment, our reality is changing. Mother Ganges, like nature, is constant, but no manifestation of hers remains. Likewise, all that we hold dear in this world is imperceptibly vanishing. We cannot cling to anything. But if we can appreciate the beauty of the underlying current of truth, we can enjoy a reality deeper than the fickle waves of joy and sorrow.

The word surrender sounds horrible to one who wants to enjoy his senses but very sweet to one who has a humble heart.
