I was once said by an elderly man that we should not touch the backside of a temple while doing pradakshina because ghosts and rakshasas live there and touching that part will wake them. Supporting this claim we also have a shloka/mantra.
उत्तिष्ठन्तु भूतपिशाचा येते भूमि भारका |
येतेष्टामविरोधेन ब्रह्म कर्म समारभे ||
uttiṣṭaṃtu bhūtapiśācā yete bhūmi bhārakā |
yeteṣṭāmavirodhena brahma karma samārabhe ||
Which randomly means asking the ghosts, rakshasas to vacate the place as we are starting a brahma karma(auspicious deed).
The above mantra is chanted before starting any pooja.
- Do ghosts and rakshasas live behind the deity in the temple?
- Do they live in our homes?
