Bhagavad Gita, Chapter 4, Verse 26

Some again offer hearing and other senses as sacrifice in the fire of control, while others offer sound and other sense-objects as sacrifice in the fire of the senses.

Some people work by holding the senses back. Others work by letting the senses meet the world differently instead.

These are two real, different approaches to the same underlying goal. One pulls the senses inward through discipline, the other lets them stay engaged with the world but changes what they're actually perceiving in it.
