It is very difficult to get out of the clutches of this maya, contamination. Very difficult. Mam eva ye prapadyante: “But one who keeps touch with Me, with full surrender,” mayam etam taranti te, “he’s out of these clutches of maya.”

So just like there is antiseptic, what is called, vaccination, to keep yourself from the contamination… There is epidemic, and under government order everyone is vaccinated, that “You take this vac…, so you shall keep your…” This is material way of keeping oneself from contamination. Similarly, if you keep always yourself in spiritual understanding of Krsna consciousness, you’ll remain pure.

(Srila Prabhupada — September 25, 1968, Seattle)
