While there was no state-level official celebration, the deputy commissioners have been directed to organise it at the district level.
"Deputy commissioners of all the districts have been directed to organise it (Yoga Day)," Chief Secretary Y Tsering told PTI.
NGOs also are organising it independently, he said.
The BJP along with the Bharat Swabhiman Trust and Patanjali Yog Samity organised a yoga camp at the J N Sports complex where over a hundred people participated.
Central government offices including Air Force, Army and the CAPFs also celebrated the day by performing yoga at their respective offices.
