Yin-yang, masculine vs. feminine

"Won't" power, "No" power - masculine

"Will" power, "Yes" power - feminine

neti, neti;

na iti, na iti - masculine

(iti, iti)

idam sarvam - feminine

Attributes and Qualities:

- reject all to reach simplicity & purity- masculine

- accept, integrate, and transcend all - feminine

Immanent Divine - masculine goal

Transcendental Divine - feminine goal

Yet, both approaches --

- diving or rising or subtilizing

to subtler and subtler, 

to more and more abstract levels within oneself

until infinity, total a-dvaita, is reached

and

- accepting 

more and more broadly, 

to more and more transcendency, 

more and more integration, 

until the simplest and purest commonality 

within all others is reached;

arrive at the same location.

One finds or dissolves into infinity within oneself.

The other finds or dissolves into the same infinity within all other selves.

Jnaana yoga - masculine

Bhakti yoga - feminine

Yet again, physical sex or gender need not and often does not match mental attitudes and approaches.

Also, both physically masculine and feminine humans 

must work both physically and mentally, 

must practise aspects of karma yoga and raaja yoga 

- neither of which fit as neatly into the yin-yang dichotomy 

as do jnaana-bhakti yoga.

Bhakti yoga is more difficult intellectually, just as integration is more difficult than differentiation :-) Finding subtler and simpler and more and more general commonality amongst more and more data, among more and more beings, is not a trivial effort.

Why bring this up at all?

Science strives to find a single or unified field from which all else emerges. In the sense above, this is a feminine approach, an integrative and simplifying method, and indeed, even an objective or saaksHI bhaava approach. However, at the subtlest levels, material or even energetic instruments are grosser than what they are to measure or observe, (IOW, direct perception), and inferencing or extrapolation becomes necessary.

The Sufis have a concept of Arc of Ascent and Arc of Descent. This approach transforms seekers by removing accretions, biases, and complexities until the Ultimate, the Absolute can work, can flow freely and without distortion through them. Ascension is the seeker's work and descending that of the Divine.

Here, as in science or in the yogas, physically-gendered activity is not an issue. Instead a gender-neutral consciousness and/or energy is purified and simplified until they can both unmanifest and manifest freely. Obviously, however, physical expression will be varied and gender-driven, and indeed unique due to the remaining saṁskāras.

In the Indian tradition, the guru tattva includes both father and mother tattvas, both masculine and feminine. A real guru then can guide both men and women, and along both depth-first and breadth-first paths.

Heartfulness does both, for all practitioners. Meditative, closed-eyes, or inward, depth-first practices, followed by open-eyed practices. Daaji puts it as actively meditating and meditatively active! Or spiritualising all normal life activities, instead of distinct meditative and non-meditative activities. Or, an arc of ascent and descent every day. Interactions with others outside of closed-eyes activities lead to a different arc of ascent - within others than within oneself.

In sum, both yin and yang, both masculine and feminine, both unmanifesting and manifesting, are needed - first for removal and then for evolution, for individual praLaya and individual sristHti.
