Sayadaw U Tejaniya's approach to meditation, which includes techniques like the "finger rubbing method," emphasizes relaxed, continuous awareness and right attitude over intense, forced effort.
The core of his teaching is about developing awareness of the mind and body in a natural, sustained way throughout all activities, not just during formal sitting.
The finger rubbing method is mentioned as an example of an object of concentration that a practitioner can use, particularly to calm and stabilize the mind for brief periods throughout the day.
Instead of only focusing on traditional objects like the breath, he suggests picking whatever serves the practitioner best in the moment to ground the mind. The sensation of one finger touching another is listed as one such possible object.
Key aspects of his overall practice style that relate to the use of such simple, flexible objects are:

• Relaxed Effort: The practice should be done in a relaxed manner without forcing concentration or effort. The finger rubbing, or any chosen object, is used with a light touch of effort.
• Continuous Awareness: The ultimate goal is to maintain awareness continuously in daily life—when sitting, walking, talking, and doing any activity. Using a simple physical sensation like fingers touching can serve as a way to quickly "drop into the present moment" and develop concentration in tiny moments throughout the day.
• Awareness of Mind State: More important than the object itself (like the fingers touching) is being aware of how the mind is feeling while observing the object—is it tense, relaxed, wanting, or distracted? The practice focuses on recognizing the attitude of the mind.
