वास्तु मण्डन (मण्डन सूत्रधार - गृह, राजप्रासाद, दुर्ग एवं नगर-वास्तु सटीक)

Ch. IV – Gṛhādiniveśaḥ 127
Saptaparṇa, Śirīṣa, Sarala, Śiva, Śilīndhra, Śālmalī, Sarpamāra, Śamī,
Ākaśābarā— These trees are most suitable for Gods but disastrous
for men.
So, with all efforts, these trees should not be brought for human
dwellings.
122. On the constellation of Dhaniṣṭhā¹ and other five stars, collection
of the wood should not be done.
123. If the house is built with one, two or three types of wood, it is
beneficial for ever, if the construction is done with various types
of trees, it is dangerous.
According to another opinion:
124. Śrīparṇī, Śiṃśapā, Sarala, Arjuna, Hāridraka, Tinduka, Padmaka, as
well as Panasa are best for construction if they are not joined
with each other.
125. Candana and Suradāru can be joined with one another but not
with other types of wood.
Now the rules for assemblage:-
126 The bottom part of a tree should not be joined with the bottom
(of another tree), as also the upper part should not be joined with
another upper part. The old part should not be assembled with a
new one, and it is auspicious if the root part is assembled with
the right and other parts of a tree. .
127. One should assemble the upper part with the lower part (of a
tree), the side branches with the middle part, the bottom part
should be arranged below, and the top above.
128. Of all the four directions, the root part should be joined in the
South-West direction (Śiva) and the upper two parts in the North
East direction. No joints should be done in a pillar and it should
also be discarded in the centre ( Brahmasthāna) .
129. In a single row the joints should be of the same type, from top to
bottom. Any deviation will lead to failure.
