BG Chap 14 - Some factors by which we are influenced by the modes

Some of the factors are: āgama, which śāstras we hear; āpaḥ, the water we drink and the types of food we eat; prajā, our association; deśa, where we live; kāla, the time of the day; karma, our activities; janma, our conditioning from birth; dhyāna, our thoughts; mantras, what we chant; and saṁskāras, the varṇāśrama ceremonies we undergo, which begin with impregnation and end with burial.
