Santan
Santan Gopal Yantra blesses childless couples with progeny. Santana Gopala is a baby form of Lord Krishna, so this is the sacred Yantra of Lord Gopal ji or Lord Shri Krishna.
Santan Ganpati Stotra is a divine request to Lord Ganesha to provide a child. It is recommended to recite this Stotra 1200 times, starting on a Tuesday and ending on the following Tuesday or from Tuesday to Friday, to achieve the desired results.
