The conflict between Samsara (Sanskrit: संसार ) and Nirvana is that it's everywhere around us in the phenominal world. Where as oneness, or Nirvana (Sanskrit: निर्वाण ) does not have a location in our time-space based manner of perception. What brings the divide them is the human tendency to create duality. This tendency is well recorded in studies of the animal mind. Ying and Yang, this and that, seperation and qualification. ex: | Good and Evil | Fine and Bad | You and me | Mind and Body |. Creating even the most basic classification of this and that, and you put between them an infinite chasm.

When our mind perceives time, it's not as a series of minutes and hours, but rather as a description of saliant events. These event's are recorded in our mind, focused, if ever, by our perceptions. The absolute plasticity limit of the mind is astounding, but guaranteed finite so long as our physiology doesn't drastically change. Even so, when a mind as at it's most fresh, clear and open, learning like a child is possible at any age.
