Whatever we receive is Information. Whatever we preserve is Knowledge. Whatever we use is Wisdom & the instrument of wisdom is our intellect.
We have to come out of our verbal-level activity, our mind-level activity, and our intellect-level activity, into pure consciousness that is meditation.
Meditation means losing our body-consciousness, to a smaller or greater extent. Meditation means losing our mind/intellect-consciousness totally. Meditation means dwelling totally in our soul consciousness... which is the purity of original consciousness itself.
If you don't have buddhi You're in Darkness. If you've buddhi You're in Light.
