Kāma Assāda Start with Phassa Paccayā Vedanā or Samphassa-Jā-Vedana
Kāma is basically vaci saṅkhāra about sense-pleasing objects (constantly thinking about those pleasures), whether it is an eye-catching object, ear-pleasing sound, tasty food, nice smell, or a body touch.
But the second bullet said: Thus we can see that kāma assāda, sankalpita rāga, mano saṅkhāra mean basically the same thing.
I think it should be vaci saṅkhāra. Thank you.
