It does not hurt weak eyes to look into beautiful eyes never so long.

This quote suggests that gazing into beautiful eyes, metaphorically speaking, doesn’t harm or strain weak ones, no matter how long teh gaze lasts. Here, “beautiful eyes” symbolize purity, goodness and strength of character. The “weak eyes,” conversely, might represent those who are morally or emotionally weaker.

The quote essentially highlights the idea that exposure to beauty and goodness does not weaken us; rather it has a healing or strengthening effect. It’s like saying being around good people won’t hurt you but will only make you better.

In terms of personal advancement in today’s world, this could be interpreted as surrounding oneself with positive influences – people who embody traits we aspire to have. No matter how weak we feel ourselves to be (in terms of courage, determination or any other quality), spending time with those who possess these qualities in abundance will not harm us; rather it can definitely help us grow stronger.

It also suggests that even if we feel inadequate or weak in some way (like the “weak eyes”),immersing ourselves in environments where excellence is demonstrated (the “beautiful eyes”) can only serve to inspire and uplift us rather than cause damage.

In essence: seek out positivity and strength – it will never hurt you but always inspire you towards personal growth and self-improvement.
