Truth for the sake of Truth, that was their clarion call.
Theirs was not an aimless adventure of a distressed and crying mind that looks for ways to be rid of any existing despair in the hope of accepting whatever that comes.
Their spiritual march was not a disgusting prompt by the torture of the mind flow; nor did they proceed as if they were running away to a distance which may hold or open up what they know not, but which they will accept, so long as they are assured of relief from the misery of the mind flow.
On the other hand, they all started with a determination to discover that ineffable Light of the Atman that was shadowed by an unreal MAyA. Not only did they march to inquire and discover, but they urged the whole humanity to march with them on the same call!
I said they did not start with a distressed and crying mind. One who started with a distressed mind was the Buddha.
But even about him, the followers of that religion speak of him only as one who went out seeking a positive state of Enlightenment and he got that Wisdom (bodha) underneath the Bodhi Tree. And that gave him the name The Buddha.
Before he sat for meditation under that tree it appears he himself said something which has become a significant shloka in ‘Lalita-vistAra’ (A life history of the Buddha).
