Based on Ki Meditation, substituting for useless Monastic Training feat in BM
Prerequisites: Wis 13
Benefits: Once per day, after resting or meditating for 8 hours, you gain a ki pool containing 1 point of ki. (If you have an existing ki pool, your ki pool increases by 1 instead.) When you meditate, select a skill in which you have at least 1 rank. As long as you have at least 1 point in your ki pool, you gain a +2 insight bonus to that skill. You may change this skill the next time you meditate. When making a skill check for the selected skill, as a free action you can spend 1 point from your ki pool to double your insight bonus to +4.
Special: Monastic Meditation can be used in place of Monastic Training or Ki Meditation to qualify for a feat, prestige class, or other special ability. You can take the Extra Ki feat to add points to your ki pool gained from this feat.
