I thought it would be nice to read along through some scriptures and discuss the passages. I have a translation of the Upanishads done by Eknath Easwaran, a teacher whom I deeply trust and love. In this book there is an introduction before each translation with some insight from Easwaran.
Verses 9 to 11 of the Easwaran translation of the Isha Upanishad are…
In dark night live those for whom
The world without alone is real; in night
Darker still, for whom the world within
Alone is real. The first leads to a life
Of action, the second to a life of meditation.
But those who combine action with meditationCross the sea of death through action
And enter into immortality
Through the practice of meditation.
So we have heard from the wise.
What a very interesting passage! It appears to say that it is not wise to pick one type of path only (action, study, devotion). It appears that you don’t get the complete picture when you focus too much on just the outside world or just the inside world. You need both action and meditation, an understanding of both the world within and the world without in order to reach enlightenment.
Krishna does say in the Gita that it is impossible to renounce action entirely; your body will continue to act through breathing and heart pumping blood, etc. That is not something to resist.
It appears that, as with everything, the right balance is necessary. Everything in the correct measure leads us to the Truth.
