We go through lots of experiences and enjoyments. We also keep seeing them; those of this birth that we know, and many more in the other births that we do not know. Each of them has left an impression in our mind. They keep running in our mind and sprout numberless thoughts.
It is like the smell that persists in the bottle in which we kept spicy asafoetida. So also even after we have gone through experiences and enjoyments, their smell persists in our mind. This is what is called VAsanA, or JanmAntara VAsanA (VAsanA that comes from other births), or SamskAra VAsanA.
What does it do? It keeps surfacing thoughts about that enjoyment and becomes the cause for further thoughts about how to have that experience again. These thoughts are the plans which the mind makes. This ‘smell’ of the past has to subside. That is what is called ‘VAsanA-kshhayam’ (Death of the VAsanA). And that is the ‘disposal of the mind’!
‘Disposal’ implies the ‘end’. What keeps running all the time has an end when it stops running. When a large flow of water is dammed, the flow stops. In the same way when the flow of the mind is stopped, it means that is the end of the mind.
