The non-canonical Gospel of Thomas, discovered in Egypt in 1945, contains a fascinating set of teachings attributed to Jesus. Some appear in the New Testament in roughly the same form, while others are unique to this text.
The teachings in the Gospel of Thomas generally emphasize experience over doctrine, a hallmark of realization. For example, in Thomas 77, Jesus says:
I am the light that shines over all things. I am everything. From me all came forth, and to me all return. Split a piece of wood, and I am there. Lift a stone, and you will find me there. (77)
To my ear, this echoes the Buddha's earlier description of the Tathagata, the one who thus comes and thus goes (AN1.xiii):
The manifestation of one person is the manifestation of great vision, of great light, of great radiance; it is the manifestation of the six things unsurpassed . . . the penetration of the various elements, of the diversity of elements . . . it is the Tathagata.
The Gospel of Thomas also contains short, direct and penetrating guidance on how to realize mind:
That which you have will save you if you bring it forth from yourselves. (70)
Similarly, the Buddha said (AN 1; iii)
I do not perceive even one other thing that, when developed and cultivated, entails such great happiness as the mind.
The teachings in the Gospel of Thomas, in their spaciousness and fluidity, seem to me to arise directly from awakened mind, the Buddha's mind.
Of course, many of these teachings have been marginalized into doctrine, a natural outcome of the human impulse toward certainty.
However, doctrine can never obscure what is right at hand. Those who seek to realize the mind of Jesus and Buddha need only go outside and lift a stone.
It's there, waiting.
Where it's always been.
