meditation to feel small in size(attain anima siddhi)
imagine your head is small, don't imagine your inside the head, just imagine a small head where your head should be keep doing this(i did this with my eyes open)
focus on the feeling you feel after and you should feel small in
size. meditate on the feeling. also try feeling how small your body feels now
this meditation worked for me, i felt like i was really short when i walked out the room after doing this.
I will say. I doubt this is that Siddhi.
Let's see at the description at first now:
"Anima – the experience of becoming extremely small or subtle. Your consciousness can perceive the creation itself."
Now more your awareness with consciousness expands due to meditation, more it can be able to perceive, more of creation you are able to perceive, smaller you see you self in existence experientially, because aside by experiencing yourself you also experience the creation around and beyond.
This Siddhi is a cause of expanded consciousness until this level where you see yourself that Small compared to the creation which is vast beyond measure.
