Bhagavad Gita 15.15
cāhaṁ hṛdi sanniviṣṭo
mattaḥ smṛtir jñānam apohanaṁ ca
vedaiś ca sarvair aham eva vedyo
vedānta-kṛd veda-vid eva cāham
sarvasya — of all living beings; ca aham — and I; hṛdi — in the heart; sanniviṣṭaḥ — situated; mattaḥ — from Me; smṛtiḥ — remembrance of the self; jñānam — knowledge; apohanam — that drives away both (forgetfulness); ca — and; vedaiḥ — by the Vedas; ca — also; sarvaiḥ — all; aham — I am; eva — alone; vedyaḥ — the knowable Absolute object; vedānta-krt — the creator, compiler of the Vedas and the deliverer of the fruits of vedic sacrifices = Vedānta; veda-vit — the knower of the Vedas; eva — certainly; ca — and; aham — I.
“I am situated in the heart of all souls as the observing and guiding Supersoul, and from Me arise the soul's remembrance of the self, knowledge, as well as forgetfulness of both. I am the creator of the Vedas and I alone am the Sweet Absolute to be known through the Vedas."
"As Veda Vyāsa, I am the compiler and revealer of the conclusion of the Vedas—the Vedānta, and I am the knower of the Vedas and the deliverer of the results of following the vedic procedures.”
Q & A: "Spirituality is not the religion?" - Spirituality is the doing of what the religiosity is looking for. If we look at religiosity as the science (of searching for the truth), spirituality is the actual doing of the science--it is the practical research, and the practice of following the spiritual principles.
Demigods and the vedas; cleansing the mind, the consciousness; Ignorance, passion and goodness; the pain caused by others--non-forgiveness, blame and retaining the pain.
