Mehsana: Lakhs of devotees are likely to congregate in the temple town of Ambaji on the auspicious Bhadarvi poonam or full-moon day. Devotees have been thronging Ambaji the entire week leading up to the poonam festivities. With many making the pilgrimage on foot, a number of volunteers have set up 24x7 stalls for Padyatris walking all the way to Ambaji.
