Time (kàla) is a sense of duration apprehended by the phenomena of change. Over the centuries Buddhist abhidhamma philosophers developed several theories of time, some of them of considerable sophistication. However, while being intellectually interesting, few of these theories have any practical application.
The Buddha’s concept of time was a purely common-sense and practical one. He spoke of two types of time – chronological time and experiential time. Chronological time can be known and measured by the regulated movement of an object. In ancient India this was done by looking at the position of the sun (M.I,393) or by measuring the movement of the sun’s shadow with a kàlatthamba or sun dial. Later, water clocks were invented which could tell the time on cloudy days and at night. Experiential time is felt through the ability to remember the past, be aware of the present and speculate about the future.
Thus in Buddhism, time is primarily a psychological phenomenon. It can also be a problematic one too. Attachment to memories can lead to regret and guilt, while speculation about the future can lead to worry, longing, fear and useless fanaticising. And both can be used as an escape from the present reality. On one occasion the Buddha said, ‘The past should not be followed and the future not desired, for what is past is dead and gone and the future has yet not come. Instead with insight let him see the present moment, the here and now. Let him know and be with that’ (M.III,187). Speaking of the value of living in the present, he also once said, ‘They do not lament over the past, they yearn not for what is yet to come but maintain themselves in the present and thus their complexion is so serene’ (S.I,5). One of the characteristics of Dhamma is that it is timeless (akàliko), meaning that it is as relevant and applicable now as it was when the Buddha taught it (M.I,137).
