I consider it as the stable phase of life. It is only the rocky edges of shallow sea that waves dance. In the high seas where there is depth the surface is calm. The current if flowing is invisible on the surface. Ships keep away from the wavy, shallow sea.
Similarly a life of sedate calmness is indicative of stability ; controlled and focused action and activity of a balanced and mature life.
In fact in our prayers we seek such a good situation where there is Shanti or tranquillity and stability.
We do not pray for turbulence, but we want Shanti and calmness. That is not the silence of inaction, but lasting stability . The Hindu Trinity also gives the 'Shaantam' of Vishnu the prime position for the 'Sthithi' status; not the Shivam of rapturous dance.
Om Shanti Shanti Shanti:
