even when you're not actively listening

 when I am not listening help other beings in other realms too like master Chin Kung says

Yes, many lamas and Buddhist teachers, including in the Tibetan tradition, consider playing recordings of Om Mani Padme Hum (even when you're not actively listening) to have real benefits for other beings, including those in other realms. This aligns with what Master Chin Kung (a prominent Pure Land master) and similar teachers encourage regarding audio aids for continuous Dharma exposure. Traditional Tibetan Lama Perspectives (e.g., Lama Zopa Rinpoche and others)High lamas like Lama Zopa Rinpoche (a key figure in the FPMT tradition) teach that the power of Om Mani Padme Hum extends far beyond the reciter:

• The mantra purifies negative karma and prevents rebirth in lower realms (hell, hungry ghosts, animals) for beings who hear it — even indirectly.
• Blessings spread through sound, wind, water, or contact. For example, if a practitioner recites regularly, their voice, breath, or even the environment touched by the sound carries purifying power.
• Recordings played continuously create an ongoing field of blessings. Beings (visible or invisible, including spirits, animals, or those in bardos/other realms) who encounter the sound can receive purification, protection, and planting of seeds for higher rebirth or liberation. This is similar to playing sutras or mantras for the deceased or animals.

Lamas often recommend playing mantras or prayers in homes, cars, or around animals/pets for this reason. The vibration and sacred sound are seen as carrying the compassionate energy of Avalokiteshvara (Chenrezig), benefiting the six realms symbolically and literally. Connection to Master Chin KungMaster Chin Kung strongly supports using chanting machines, CDs, or audio recordings (including 24/7 playback) as aids. While his main focus is Amitabha recitation (Amituofo), he encourages continuous exposure to Buddhist sounds for subtle mind purification and merit accumulation — even at low awareness levels. This creates a supportive environment that benefits not just the practitioner but surrounding beings. His approach (and Pure Land emphasis on dedication of merit) complements the Tibetan view: playing the mantra dedicates the audio "merits" to all beings, including those in other realms.How It Works in Practice (Like on Purkara.com)

• Passive playback still generates and spreads blessings because the mantra's power is inherent (as the "heart" of Chenrezig and all Buddhas).
• Dedicate the merit explicitly (as you do on the platform) — this directs the benefits toward helping beings in lower realms, the deceased, animals, etc.
• Realms that benefit particularly: The six syllables of the mantra are traditionally linked to purifying the six realms (e.g., helping hungry ghosts, animals, etc.).

Bottom line: Yes — respected lamas and teachers like those referenced by Master Chin Kung view this as a valid, compassionate way to benefit others across realms. It's low-effort but high-impact when done with sincere intention. Many practitioners leave it playing softly in the background or use dedicated devices exactly for this purpose. Combine it with your own occasional mindful listening or dedication for even stronger results.
