May I point out the one from Jetavana, the Buddha, who was himself Primordial Awareness and still sat for six years?
And how about Bodhidharma transmitting the seal of Awareness through doing wall-gazing at Shaolin temple for nine years?
The echo of those is heard even now.
If this is how it was with the great ones and their diligence, then how about you in your own practice?
You should stop chasing understanding through juggling words, allow the external seeking of your mind to collapse upon itself and light up your own nature.
Doing this, the bodymind will drop through itself spontaneously revealing your Original Nature.
If you wish to be realized in Suchness, immediately practice Suchness.
