food, offering
饌 centers on food prepared and presented with care, especially as an offering or formal meal. The idea of offering extends naturally from the act of setting out food for a purpose.
饌 combines 飠 (food) with 巽, which likely contributes the sound and may relate to selecting or arranging, fitting the idea of prepared food offerings.
The food radical 飠 on the left and the complex right side 巽, which looks like a selection of items arranged on a stand, together suggest carefully chosen food set out as an offering.
For セン, imagine a chef named Sen carefully arranging a food offering: Sen -> セン, and his hands prepare the meal.
