Those ancient lead pieces have been pre-blessed by a group of Lersies (jungle hermits) with "Taecho Kasin" (concentrated meditation on fire) preparing for Thakradan making.
They are hottest and so powerful - will destroy all kinds of evils and burn all kinds of weapon unusable.
LP Lamyai's Thakradans are economy in price but a best substitution to an expensive multi-million THB ancient Thakaradan of 700 years of age for KongKraphanChatri (invulnerability) property.
They are best for police, military personnel, security persons, logistic team, advance unit, rescue unit, debt collection unit, explorers, etc.
LP Lamyai Thakradans were struck on the old ancient lead pieces. So, they have sharp and clear filigrees.
Lead oxide, red-brown lead rust, or both is still be seen on the surface of some of LP Lamyai's Thakradans.
LP Lamyai blessed his Thakradans for a Trimas (3-month Buddhist lent period) before giving as gift to people who donated for temple construction and renovation projects.
ANCIENT TAKRADANS & LEFTOVER LEAD PIECES:
Old ancient Thakradans are one of a few top famous amulets of the country for invulnerbility.
They were created with pre-blessed lead by a group of Lersis (hermits) in B.E.1800 or around 700 years ago .
Thakradan amulets were found in 6-7 old ancient temples in Srisawas District, Kanchanaburi province, in late 2480s to mid 2490s. Only 500-600 pieces were found altogether.
By later exploration and excavation in Srisawas District, holy leftover pre-blessed lead pieces of 4-5 cm diameter have also been found there.
MIRACLE PHENOMENA:
A long years before old ancient Thakradans and their leftover lead pieces were found, local hunters in Srisawas District had shot guns in the areas to kill animals but always misfired amazingly - bullets could not discharge from guns.
Later, a meditative monk disclosed the secret to those hunters that the gun misfires due to the invulnerable power of Thakradan amulets scattering over those areas.
