If we could analyze the excitements and anguish that we possess to the tiniest details, it is exactly the same effect as that of the sea waves that keep pushing forward and fading away on top of the sea surface repeatedly. Our emotions rely on our physical body (form aggregate) and the sensation aggregate, perception aggregate, formation aggregate and vijnana aggregate to actualize.
The important point here is that we have to establish a correct concept, if something arises dependent on conditions, a condition-arisen dharma, it is essentially an existence without intrinsic nature, and it is impermanent and will eventually cease to exist once the conditions fail to support it any more.
The sea waves will cease to exist once there is no more sea water. Because it is a dharma of changing, from nothing becomes of something via conditioned elements; then it will change again, from existing to nothing when the conditioned elements disappear. Behind all the arising and ceasing of existence, there is an everlasting entity to support all the phenomena. Otherwise, the whole existence of logic would collapse. Every mortal living being innately possesses his own Alayavijnana, that is why every individual has to cultivate his own path to attain liberation or Buddhahood, the same way as each and every one of us has to take our own lessons to study in life.
If we are able to fully comprehend the functions of the eighteen sense-realms 十八界, then we will understand that our physical body and the perceptive mind also belong to the condition-arisen dharmas. In other words, the conscious mind that every individual totally relies on while alive exists only one lifetime, it cannot proceed to future lives.
