Hi Mike,
Thank you for your comments and for mentioning Dalio. In his 'Principles' he says that any alpha he has ever generated is owed to his meditation practice. Though, it is just a brief mention. More recently he has been more forthright in discussing his practice.
I have studied many different forms of meditation, including breath, mantra, present moment awareness, creative visualization, mindfulness, and others. This tends to be how I explore subjects: starting very broadly and then discovering what works for me. I wish I could say that I learn things quickly, but instead it is usually a laborious process.
With smiles,
Jason
