Here is a quick practice for calling on compassion for the self and muting the inner meanie:
Singing along with any mantra will bring you into a more positive place, but Kundalini Yoga offers a gorgeous English mantra that really clearly and directly builds self-love: “Beautiful Am I, Bountiful Am I, Blissful Am I.”
The three musical renditions of this mantra that I love best are: "Beautiful Am I" on Aykanna’s Livelight;“Bountiful, Beautiful, Blissful” on Harnam Singh’s A Fearless Heart; and “Bountiful, Blissful, Beautiful” on Bachan Kaur’s Angels in the Amrit.
Just play them, sing along, enjoy, and believe.
