Sitz des Bewusstseins und des Göttlichen Selbst:
"Therefore as soon as the mind reaches the heart [its core and essence, which is pure awareness] [by] inwardly investigating who am I in the above [exalted] manner [or way], when [thereby] he who is ‘I’ [the ego] dies, one thing [or the one] appears spontaneously [or as oneself] as ‘I am I’ [that is, as awareness of oneself as oneself alone]. Though it appears, it is not ‘I’ [namely ego]. It is poruḷ-pūṉḏṟam [the entire substance, whole reality or pūrṇa-vastu, which is eternal and unchanging], the poruḷ [substance or vastu] that is oneself."
Upadēśa Kaliveṇbā lines 124-128: the extended version of Uḷḷadu Nāṟpadu (the Spiritual Teachings of Bhagavan Sri Ramana)

Aktiviertes Herzzentrums:
"Die Identität von Shiva/Shakti, das Erschauern im Herzen des Yogis ist der Nicht-Weg, der vom Herzen ausgeht und sich ins Herz ergießt, unaufhörliche Bewegung von Kontraktion und Extension. Das ist Shivas/Shaktis Atmung in mir." S.68
