According to Osho, ‘guru’ is a neutral term—any teacher, true or false. A sadguru is the true guru: one who speaks from direct seeing, not borrowed scriptures; whose inner lamp is lit and whose words carry living nectar. The pseudo-guru repeats tradition, shows pictures of light but gives none. Choose the one whose presence illumines and transforms.
A sadguru is the real teacher who has seen truth and shares his own light, while an ordinary ‘guru’ might just repeat others’ words.
