Since the king had no children from his main consort, the young brother-in-law of the king was the next in line for the throne of Kandyan Kingdom. With the appointment of Vijaya Rajasinghe to the throne in 1739, Welivita Sri Saranankara had the opportunity to make a direct influence to the king. He managed to persuade the king by 1741 to negotiate with the Dutch, who were ruling maritime provinces to accommodate a delegation to Siam (now Thailand), to revive the higher ordination, Upasampada. The king got the assistance of the Dutch to send a delegation to Siam, which was unsuccessful. Several members of the delegation died when the ship they traveled sank on the way while the survivors returned to Sri Lanka. A second delegation which was dispatched in 1745, led by one of the survivors of the first delegation successfully reached Siam, but could not conclude the negotiations due to the untimely death of the king Vijaya Rajasinghe. The King of Siam was reluctant to send Siamese monks to revive the monastic lineage of Sri Lanka without knowing what the attitude of the new king would be in this matter. After the demise of King Vijaya Rajasinghe in 1747, Kirti Sri Rajasinha was appointed as the King of Kandyan kingdom. The reign of king Kirti Sri Rajasinha brought a new energy to the revival of Buddhism in Sri Lanka. Weliwita Sri Saranankara Samanera extended his fullest corporation to the new king who depended on him for advice, guidance and inspiration. He urged the king to send a third embassy to Siam with the help of Dutch East India Company for the revival of Upasampada. The third delegation which left Kandy in July 1751 made it to Trincomalee and left Sri Lanka's shores later in the same month. The mission was successful and the king of Siam Borommakot accepted the request of king Kirti Sri Rajasinha and sent a delegation of twenty, headed by Upali Maha Thera to Sri Lanka. Two years later the delegation with Upali Thera was able to set sail back to Sri Lanka and reached Trincomalee in May 1753 after leaving Siam in January, 1753. The delegation which was headed by Upali Thera, composed of higher ordained Siamese monks, who entered Kandy in June 1753. At the age of 55 years, Weliwita Sri Saranankara Samanera received the 'upasampada' and qualified as a higher ordained monk on the Esala poya day in 1753 at the Malwatu Maha Viharaya.
