There’s 3 Gs we need to catch hold of very tightly for spiritual progress.
1. God
2. Guru
3. Gita, aka our scriptures
These in isolation won’t help much unless they are bound by our own self-effort. We will have to ourselves go through the Grind, which can be the fourth G in this package.
God-Guru-Gita-Grind
That’s about as clear as it gets!
