It reminds me of this:世尊在靈山會上拈華示眾眾皆默然唯迦葉破顏微笑世尊云
The Lord dwelt at the Vulture Peak with the assembly and plucked a flower as a teaching. The myriad totality were silent, save for Kāśyapa, whose face cracked in a faint smile. The Lord spoke.
I have the treasure of the true dharma eye, I have nirvāṇa as wondrous citta, I know signless dharmatā, the subtle dharma-gate, which is not standing on written word, which is external to scriptures, which is a special dispensation, which is entrusted to Mahākāśyapa.
"Like a hawk, flying high above and preying on others, and yet outwardly displaying justice, worship, wisdom, and faith — this is raising up the lowest order of good, and walking the way of the demons".
There is no secret in the Early suttas.
Only the meaning has been corrupted by demons, petas, and yakkhas.
And as the Buddha used to say, you can arrive to certain states, starting with wrong view, (like being initiated by those who are born with them: https://justpaste.it/59hb4 )
Am I wrong ?
