Fulfilling desires will never lead to Poornatvam.

We want to be happy in life. To be happy we feel that we fulfill all our worldly desires such as completing school, Getting admission in good college, getting a job, amassing wealth, getting married, begetting children, seeing the world, getting admission to children in good school, cycle continues, it will never end. Growth of desire is exponential, it will never subside. So thinking that fulfilling all our worldly desires will render us complete is a wrong concept. You will remain only finite; never become infinite which is a state of complete Ananda, total bliss.

Not only your desires grow at a pace beyond control, it has six byproducts, viz, Kama, Krodha, Lobha, Moha, Madha& Matsarya, which will delude your mind so that all your decisions will be wrong one.

The onslaught of desire is well explained in the following verse from Vairagya Satakam, written by the great Hindu philosopher Bhatrihari containing 100 verses:

The desire of people is like a river which is flowing continuously. It is like fancy, very silent at the initial stage. At times they are like turbulent rivers with waves of craving. Desires are grasped & become an attachment. Like birds flying over the river on & off, doubts come in the mind whether I can do it or not. Desires bring along diffidence along with that after years of failure, leading to fatalistic attitude. Desires bring in whirl pool of delusion. More desires mean more delusion, discriminating power is clouded. When the desire is very deep, it is not possible to cross the river of desire. There are two high banks of the river of desire, such as worry & pain. Viragis, who have Vairagyam with pure mind revel in that state & cross the river of desires.
