They worship demigods or some powerful man of this world because they want quick results in their fruitive acts
One who worships Krishna for material benefit, does obtain his desire, but first Krishna purifies his heart. Purification may take some time. Also when reward is achieved devotee no longer wants it e.g. Dhurva Maharaja
Analogy: Boons of demigods are like bubbles in Cosmic Ocean
aAre demigods equal to God? — No, To consider so is “Pashandi” or atheist mentality
They are parts and parcels – Ref. Brahma-samhita / Vedas
They are living entities with material powers
Even Brahma and Siva worship Vishnu
Meaning of ‘Iha-devatah’ – Any powerful man or demigod in this material world
bNarayana or Visnu does not belong to the material world — Ref. Sankaracharya
cMadness of human society
Mad after temporary things
Worship temporary leaders – Kowtowing to so called big-guns
Not interested in Krishna consciousness for permanent solutions
dConclusion — People are rarely interested in Krishna consciousness
LINK BETWEEN TEXTS 4.12 & 4.13 — Some worship demigods, some worship Brahman, some worship Krishna. Thus Krishna the Supreme Isvara controls everyone’s desires. Is He responsible for the suffering and enjoyment of everyone in this world? How can such people become free from excessive attachment?
