For individual kalyan (welfare), physical form may become necessary. Jagat kalyan (world welfare) can be done in physical or astral form. Mahavtaar Babaji does jagat kalyan in physical form. Siddhnath Baba does individual kalyan as well as jagat kalyan. He is in Siddhgiri in Girnar. He does jagat kalyan in form of sankalp (resolution).
For individual kalyan, guru may come for you. Sometimes you may come in contact with such a saint. If you remain connected with such a saint, then you can attain moksha (liberation), such saint may have come for jagat kalyan and not individual kalyan, but by your connection you can attain moksha. Tirthankara (one who is liberated and also leads millions to liberation) would do individual kalyan as moksha in form of jagat kalyan to million on physical plane.
