	DELTA POWER
	Multiple comparisons with FDR correction	20 × 4 × 2 mixed ANOVA	4 × 4 × 3 mixed ANOVA
First set of meditative practices, performed by all practitioners (N = 16)	M1: Decrease in F7 (p = .07) M2: Decreases in Fz (p < .05), F4 and Fp2 (ps = .06) Yidam: Increases in F8 and T4 (ps = .06)	Sig effect of Practice, F(3, 42) = 2.84, p = .049, ηp2 = .17; sig decrease during M2,F(1.14) = 5.03, p = .04, ηp2 = .26  Sig effect of Electrode,F(19, 266) = 2.56, p = .000, ηp2 = .15 with higher power in Cz than in O1, O2, P3, P4 and higher power in Fz than in P3 (ps < .05) No sig effect of Tummo Expertise, F(1,14) = 3.21, p = .09. Non-sig effect of Meditation Experience, F < 1, p = .44	Sig effect of Region, F(3, 45) = 5.19, p = .004, ηp2 = .27, with higher power in the frontal and central regions than in occipital, ps < .05 Sig effect of Lateralization, F(2,30) = 8.40, p = .001, ηp2 = .38; midline power is higher than left and right (p < .05) Marg Practice X Lateralization, F(6,84) = 2.03, p = .07, ηp2 = .13, with the effect of Lateralization more pronounced during meditative practices than rest
	Multiple comparisons with FDR correction	20X5 repeated measures ANOVA	5 × 4 × 3 repeated measures ANOVA
All practices performed by Tummo experts (N = 10)	M2: Decreases in F3, C3, Cz, T3, P3, P4 (ps < .05), F4 and in Fp2 (ps < .07) Tummo: Increases in F3, F7, F8, Cz, C4, P3, P4, Pz, POz (p < .05) and in Fp1, C3, T3 and T4 (p < .06)	Sig effect of Practice, F(4,36) = 4.41, p = .005, ηp2 = .33; sig decrease during M2, F(1,9) = 12.37, p = .007, ηp2 = .58; and sig increase during Tummo,F(1,9) = 17,57, p = .002, ηp2 = .66 Sig effect of Electrode, F(19,171) = 2.10, p = .007, ηp2 = .19 with power higher in Cz than in P3 and T5 (ps < .05) Sig Practice X Electrode, F(76, 684) = 2.11, p = .000, ηp2 = .19	No sig effect of Region, F(3, 27) = 1.89. p = .16. Sig effect of Lateralization, F(2,18) = 3.95, p = .04, ηp2 = .31 with midline power higher than left (p < .05)
