Rishi Patanjali describes 'smriti' as the modification of mind where memories of past experiences do not fade away. All these experiences create ripples in the mind as memories and reminiscences, keeping it engaged in the unreal and keeping us away from the real.

It is memory which unites us with people or events. It connects us to everything we consider our own. This memory is the result of our everlasting desires, which we are unable to let go of. It resides in every cell of our being.

Yoga teaches one to stay in the present moment, where no memory (past or future) stimulates the brain. Our memories age us, yogis are able to sustain thoughts and arrest ageing. Keep no memories.
