What is ‘yashti’ and ‘samashti’ ?

Q: What is ‘yashti’ and ‘samashti’ ?

*Gurudev Sri Sri :*

Do you sing daily? (The lady said that she sang at home when alone.)

When you sing alone, that is yashti. When you sing with everybody here, participate in the bhajan with everyone that is samashti.

Samashti means the entire creation.
