Worshippers of Deities  

• Ye'pi anya devata bhakta yajante shraddhayanvitah, Te'pi mam eva kaunteya yajanty avidhipurvakam (BG Ch 9, Sl-23) 
  Those who worship the Deities (God's lower manifestations ) with faith, that worship is also My worship though done not in the right way. The right way to worship God is not in the form of any of His manifestations as a Deity but in His infinite, Nameless and Formless aspect. Nevertheless He accepts all worship of Deities as indirect worship of Him. 

• Yanti devabratah devan, pitrin yanti pitrivratah, Bhutani yanti bhutejyah madyajjinopi mam. (BG Ch 9, Sl-25) 
  Those who worship the Deities go to the high astral worlds of the Deities; those who worship the ancestors go to the lower astral worlds where the ancestors dwell. Those who worship the ghosts or the lower demonic spirits or the elemental spirits go to their places. Those who worship God in His transcendental aspect reach the transcendental abode.
