Premanand Maharaj Ji
How should a daughter or son truly serve aged and sick parents?
Physical care first, then bhajan
Do both, but bathing, clothing, feeding and giving medicine come first, with bhajan (devotional singing and prayer) for their welfare second. Clean their mess gladly, just as we once soiled our mother's lap.
For aged parents, bathing them, dressing them, feeding them and giving medicine is the main service, and doing bhajan for their highest good is the second.
