PS here refers to Problem Solving.
Meditation PS? Yes, because most people, me first on the list, struggle with some important stuff.
Like how to keep the mind calm and focused? Answer: it’s not possible, because that is the nature of the mind. Advanced yogis can, but not without deliberate practice, which is what made them advanced yogis in the first place. For most others, even after brief meditative spells, they will crash right back into the plane of desires and attachments.
What to do? Catch hold of your Guru or Ishta Devata. Not physically, but mentally. And try to meditate on topics related to them, if not on them only. This gives some freedom to the monkey mind, while still keeping it on a leash. It helps if we truly recognize and believe that everything we are today, and everything we will be tomorrow, is entirely because of the Guru and/or the Ishta Devata. They are both the same at their core, so choosing one over the other doesn’t matter. If we feel deep down that everything is because of them, then where is the question of our ego, and hence our desires and attachments?
