The Satipatthana sutta (Majjhima Nikaya 10, Digha Nikaya 22) instructs the beginning practitioner to contemplate subjects internally and externally, then making a comparison:
““In this way he remains focused internally on the mind in & of itself, or externally on the mind in & of itself, or both internally & externally on the mind in & of itself.”
Contemplation of pacceka-buddhas should in some way be connected with the practitioner’s own practice. This would be through frugality of speech, isolation of living, and study of thudong practices:
